Question

What percent of 225 is 99?

Answer 1

I'll help you get started:
The general formula for these is:
\[\dfrac{part}{whole} = \dfrac{\%}{100}\]
After inputting the given values you have
\[\dfrac{99}{225} = \dfrac{\%}{100}\]

The percent is what we need to find so label that x:
\[\dfrac{99}{225} = \dfrac{x}{100}\]

Now cross multiply and solve for x. Let me know if you have any questions.
