To simplify, look at the denominator. There's a 100 in the denominator. And, 100 has two zeros at the end. In the numerator, we have 4500. 4500 has two zeros in the end as well. First, cancel out the two zeros in 100 to make it 1. Then, to make the fraction even, cancel out the two zeros in 4500 to make it 45. It should now look like this: .
