Greetings! 

We can create an equation that can be used to solve problems of this kind:
[tex]90= (\frac{70}{100})x[/tex]
Let x represent the number.

Solve for x.
[tex]90= \frac{70}{100}x[/tex]

Divide both sides by [tex]\frac{70}{100}[/tex]
[tex]\frac{90}{\frac{70}{100}}= \frac{\frac{70}{100}x}{\frac{70}{100}} [/tex]

[tex](\frac{90}{1})({\frac{100}{70}})=x[/tex]

[tex]\frac{9000}{70}=x[/tex]

Reduce the fraction to lowest terms or a decimal
[tex]\frac{900}{7}=x[/tex]

The Answer Is:
[tex] \left[\begin{array}{ccc} x=\frac{900}{7}\end{array}\right] [/tex]

70% of [tex]\frac{900}{7} [/tex] is equal to 90.

Hope this helps!
