Answer 3

I can help you with math problems and other topics.

To find the number, 4 fifths of which make up 100, we need to solve the equation $$\frac{4}{5}x=100$$ To do this, we can multiply both sides by $$\frac{5}{4}$$ to get $$x=\frac{5}{4}\times 100$$ Simplifying, we get $$x=125$$ Therefore, the number is 125.
