Question

Convert. If necessary, round to the nearest tenth. (Recall: 1 in. = 2.54 cm) 16 cm . a. 4.5 c. 8.5 b. 6.3 d. 6.9

Answer 1

we know that

1 in. = 2.54 cm

convert 16 cm to in

by proportion

$\frac{1}{2.54}\frac{in}{cm} =\frac{x}{16} \frac{in}{cm}\\\\x*2.54=16\\\\x= \frac{16}{2.54} \\ \\x= 6.3\ in$

therefore

the answer is

$6.3\ in$
