Start by rewriting the complex fraction as a division problem.

2/25

Practice makes perfect

We want to simplify the following expression. 45/10 As we can see, we have a complex fraction. Let's rewrite it as a division problem. 45/10 = 4/5 ÷ 10 Now we can write the division by 10 as multiplication by the reciprocal of 10, which is 110. 4/5 ÷ 10 = 4/5 * 1/10 Finally, let's evaluate the expression.

4/5 * 1/10
