Since there are $100 \mathrm{~cm}$ in $1 \mathrm{~m}$, then $1 \mathrm{~cm}$ is $0.01 \mathrm{~m}$. Thus, $3 \mathrm{~cm}$ equals $0.03 \mathrm{~m}$.

Since there are $1000 \mathrm{~mm}$ in $1 \mathrm{~m}$, then $1 \mathrm{~mm}$ is $0.001 \mathrm{~m}$. Thus, $5 \mathrm{~mm}$ equals $0.005 \mathrm{~m}$.

Therefore, $2 \mathrm{~m}$ plus $3 \mathrm{~cm}$ plus $5 \mathrm{~mm}$ equals $2+0.03+0.005=2.035 \mathrm{~m}$.

ANSWER: (A)
Which of the following is equal to $2 \mathrm{~m}$ plus $3 \mathrm{~cm}$ plus $5 \mathrm{~mm}$ ?
(A) $2.035 \mathrm{~m}$
(B) $2.35 \mathrm{~m}$
(C) $2.0305 \mathrm{~m}$
(D) $2.53 \mathrm{~m}$
(E) $2.053 \mathrm{~m}$
