Hey!
--------------------------------------------------
When you multiply fractions you just multiply across.
When we have 5/100 x 75/100 we turn it to 5*75/100*10
After solving we get 375/10,000
To simplify we need to find the GCF. In this case it's 125.
375÷125/10,000÷125 = 3/80
--------------------------------------------------
Hence, the answer is
