Question

What is 99/100 over 21 in simplest form

Answer 1

If you divide a fraction over a number, you can just muplitply the denominator (the number under the line) by the number by which you divide:

$\frac{99}{100*21}$

99 and 21 are divisible by 3, so we can divide them both by it:

$\frac{33}{100*7}$

but that's all we can do!

so let's multiply

$\frac{33}{700}$

and it's its simplest form
