Answer:
91%
Step-by-step explanation:
We can use the formula [tex]\frac{is}{of}=\frac{percent}{100}[/tex]
- "is" is 90
- "of" is 99
- "percent" is what we are solving for so we will denote it as x
Substituting in our values we get [tex]\frac{90}{99}=\frac{x}{100}[/tex]
- We will need to cross multiply here to get (90)(100) = (x%)(99)
- This simplifies to 9000 = 99x%
- Dividing by 99 on both sides we get 90.9% → x = 91%
