Question

Please show all your work when solving this problem. Thank You! 0.8:10 :: x:100

Answer 1

Answer:

Given the following equation:

0.8 : 10 = x : 100

We have to find the value of x.

It can be written as:

$\frac{0.8}{10} =\frac{x}{100}$

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

Answer 2

0.8/10 = x/100
$\frac{8}{100} = \frac{x}{100}$
Cross multiply.
100x = 800
x = 8
