Firstly, change the whole number 1 into fractions (as shown in the picture).
As the fractions multiply each other, the denominator of the first fraction cancels off with the numerator of the second fraction (as shown in the picture). For example, the denominator of the first fraction (100) is cancelled off with the numerator of the second fraction (100).
The final answer will then be the numerator of the first fraction in the question (99), and the denominator of the last fraction in the question (200).
