Question

What is 18/48 simplify

Answer 1

Hmm they're both even numbers so maybe we can start by cutting each number in half.
$\rm \dfrac{18}{48}=\dfrac{9\cdot2}{24\cdot2}=\dfrac{9}{24}$
18 and 48 had 2 as a common factor.
So factoring a 2 out of each number was the same as cutting each number in half. Try to do something similar with the 9 and 24. They each have something in common.

Answer 2

The answer to your question is 0.375
