Question

Solve the proportion using cross products. Round to the nearest hundredth if necessary. 12 miles/27 hours = 4 miles/ h hours

A. 28
B. 12
C. 9
D. 18

Answer 1

C.9

Explanation:

We are given that

`(12)/(27)=(4)/(h)`

We have to find the value of h using cross product.

`(12)/(27)=(4)/(h)`

By cross multiply we get

`12h=27* 4`

After multiply we get

`12h=108`

`h=(108)/(12)`

Using division property of equality

`h=9`

Hence, option C is true.
