Answer:

The answer is a = 99

Step-by-step explanation:

We can solve this using ratios

First we set up the equation:

[tex]\frac{a}{90}= \frac{110}{100}[/tex]

Then cross-multiply:

[tex]100 * a = 90 * 110[/tex]

Simplify:

[tex]100 * a = 9,900[/tex]

Divide both sides by 100:

[tex]a = 99[/tex]

Ta-Da! The answer is a = 99

Hope this helps! :)
