What is 99/100 over 21 in simplest form
Likurg_2 [28]
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
