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

`(1)/(2.54)(in)/(cm) =(x)/(16) (in)/(cm)\\\\x*2.54=16\\\\x= (16)/(2.54) \\ \\x= 6.3\ in`

therefore

the answer is

`6.3\ in`
