Answer:
Given the following equation:
0.8 : 10 = x : 100
We have to find the value of x.
It can be written as:
[tex]\frac{0.8}{10} =\frac{x}{100}[/tex]
By cross multiply we have;
[tex]0.8 \cdot 100 = 10x[/tex]
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
