What percent of 99 is 90?
Yuri [45]

Answer:

91%

Step-by-step explanation:

We can use the formula \frac{is}{of}=\frac{percent}{100}

  • "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 \frac{90}{99}=\frac{x}{100}

  • 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%
