Greetings!
We can create an equation that can be used to solve problems of this kind:
\(90= (\frac{70}{100})x\)
Let x represent the number.
Solve for x.
\(90= \frac{70}{100}x\)
Divide both sides by \(\frac{70}{100}\)
\(\frac{90}{\frac{70}{100}}= \frac{\frac{70}{100}x}{\frac{70}{100}}\)
\((\frac{90}{1})({\frac{100}{70}})=x\)
\(\frac{9000}{70}=x\)
Reduce the fraction to lowest terms or a decimal
\(\frac{900}{7}=x\)
The Answer Is:
\(\left[\begin{array}{ccc} x=\frac{900}{7}\end{array}\right]\)
70% of \(\frac{900}{7}\) is equal to 90.
Hope this helps!
