- Definition of Reciprocal. If the product of two numbers is 1, then the two numbers are said to be reciprocals of each other. In other words, a reciprocal is the multiplicative inverse of a number. Examples of Reciprocal. The real part of a complex number Z is denoted as Re (Z). 1/9 is the reciprocal of 9.

CBSE Class 11: Chemistry - CH1 - Laws of Chemical Combinations Answer: Law of reciprocal proportions states, When two elements combine separately with a fixed mass of a third element, then the ratio of their masses in which they do so is either same or some whole number multiple of the ratio in which they combine with each other. Q15: Who proposed law of reciprocal proportions.

- Put this together with the sign change, and you get that the slope of the perpendicular line is the negative reciprocal of the slope of the original line — and two lines with slopes that are negative reciprocals of each other are perpendicular to each other.

Multiplicative Inverse: Definition, Property & Examples A multiplicative inverse is a reciprocal. A reciprocal is one of a pair of numbers that when multiplied with another number equals the number 1. When we ask what the multiplicative inverse of a number n is, we are asking what number when multiplied with n will give us 1.

- So, the reciprocal of x is 1/x, and the reciprocal of 1/x is 1/(1/x) … = x. (Taking the reciprocal of the reciprocal of a number yields the original number.)   Examples:   * The reciprocal of 2 is 1/2.  * The reciprocal of 1/2 is 1/(1/2) = 2.  * The reciprocal of 3/4 is 1/(3/4) = 4/3. reciprocal is the result you get upon reciprocating something,  where to reciprocate is to calculate 1/x, with x the thing to be  reciprocated.   The reciprocal of 2 … is 1/2, that of x2+376x is  1/(x2+376x).

reciprocal Reciprocal describes something that's the same on both sides. If you and your sister are in a big fight on a long car trip, you might resolve it through a reciprocal agreement that you'll stop poking her and she'll stop reading road signs out loud.

- Note that you do not see an exponent written with the number 5. This means that the exponent on 5 is understood to be 1. Since it doesn't have a negative exponent, we DO NOT take the reciprocal of 5. The only base that has a negative exponent is a, so a is the only base we take the reciprocal of.

Angles, and More Lines Numbers whose product are -1 are termed negative reciprocals. If the slope of one line is -x and the slope of another is 1/x, then -x • 1/x = -1. Perpendicular lines, of course, always form 90° angles. Other terms for perpendicular are: orthogonal, normal, and, of course, right.

Reciprocal of a Fraction We call the top number the Numerator, it is the number of parts we have. We call the bottom number the Denominator, it is the number of parts the whole is divided into.

- Report Abuse. dividing by a fraction is same as multiplying by its inverse, so: 2/3 divided by 4/5 is the same as 2/3 * 5/4 Multiply the numerators: 2 * 5 = 10 Multiply the denominators: 3 * 4 = 12 Your answer is therefore 10/12, but in its lowest term, this is 5/6, since both 10 and 12 can be divided by 2.irst there is a trick to help you do this. 2/3 divided by 4/5 turns into 2/3 x 5/4. you just use a reciprocal. then you multiply the numerators (2x5=10 and then the denominators (3x4=12) so your answer would be 10/12 which if u divide by 2, it will reduce it to 5/6.

How to Divide Fractions by a Whole Number 6. Multiply the numerators and denominators of the fractions. Therefore, the next step is to multiply the numerators and denominators of the fraction to get the new numerator and denominator of the final answer. 1  To multiply the numerators, just multiply 2 x 1 to get 2.. Write the reciprocal of the whole number. To find the reciprocal of a number, simply switch the numerator and the denominator of the number. Therefore, to find the reciprocal of 4/1, simply switch the numerator and denominator so that the number becomes 1/4.

reciprocal A reciprocal is a pair of numbers (such as 5/6 and 6/5) that can be multiplied to produce 1. Reciprocity (with the accent on the third syllable) between two nations means they agree to recognize certain things granted in one country as being valid in the other—for example, your driver's license.

What is the quotient of a fraction? Otherwise, the quotient is basically the outcome of division.<br /><br />Let us take the example of 2/3÷3/5<br /><br />To divide with a fraction, you must simply find the reciprocal of the fraction that you're dividing by. That is to say, the opposite of the fraction, by switching the numerator and the denominator.

Multiplication Multiplication (often denoted by the cross symbol  × , by a point  ·  or by the absence of symbol) is one of the four elementary, mathematical operations of arithmetic; with the others being addition, subtraction and division.ne of the main properties of multiplication is the commutative property, adding 3 copies of 4 gives the same result as adding 4 copies of 3: The multiplication of integers (including negative numbers), rational numbers (fractions) and real numbers is defined by a systematic generalization of this basic definition.

INVERSE INSTRUCTIONS The denominator will be the numerator of the first factor. The numerator of the multiplicative inverse is 2 and the denominator is 3. This gives an answer of: All the examples in Reciprocal demonstrate that a number multiplied by its inverse gives a product of 1.NVERSE INSTRUCTIONS. Two numbers are multiplicative inverses of each other if the product of the numbers is one (1). Multiplicative Inverse is similar to the program MULTIPLY FRACTIONS except that you are to determine the second factor, which will be the multiplicative inverse of the first factor.

What is 1/2 divided by 3/4 in fraction form?? Please Help, I am completely stuck!!!!!!!!!!!!!? Best Answer: Ok, well you may or may not know that dividing by something is the same as multiplying by it's reciprocal (which is basically the number flipped). The reciprocal of 3/4 is 4/3. So, 1/2 divided by 3/4 is the same as 1/2 times 4/3. Which, if you don't know how to multiply fractions, is (1X4)/(2X3). or 4/6.If we divide both 4 and 6 by two, we get... (4/2)/(6/2) which is 2/3. So, the short answer to your question is 2/3.o, 1/2 divided by 3/4 is the same as 1/2 times 4/3.

- The complement is the amount you must add to something to make it whole. For example, in geometry, two angles are said to be complementary when they add up to 90°. One angle is said to be the complement of the other. In the figure below, angles PQR and RQS are complementary. RQS is the complement of PQR.

What does the word complement means in mathematics? The complement of a number is another number in which each digit, when added to the corresponding digit in the original number, will add up to the largest digit of the base in which the number is expressed.That sounds far more complicated than it really is. It's easier to understand by working through it.n other words, each digit, added to it's corresponding digit in the complement, should total 9. So the complement of 1976 would be 8023. Perhaps a better example would be the number 9876543210. It's complement would be 0123456789.
