0.8:10 :: x:100

Answer 1

0.8/10 = x/100

`(8)/(100) = (x)/(100)`
Cross multiply.
100x = 800
x = 8

Answer 2

Given the following equation:

0.8 : 10 = x : 100

We have to find the value of x.

It can be written as:

`(0.8)/(10) =(x)/(100)`

By cross multiply we have;

`0.8 \cdot 100 = 10x`

Simplify:

80 = 10x

Divide both sides by 10 we have;

8 = x

or

x = 8

Therefore, the value of x for this problem is, 8
