This worksheet helps you learn how to make fractions smaller when they’re made of odd numbers.

Each fraction comes with two lists of numbers you can divide it by. One list is for the top number (numerator) and one is for the bottom number (denominator).

Your job is to find the biggest number that both the top and bottom can be divided by. Then, you divide both numbers by this big number to make the fraction as simple as possible.

For instance, they give you the fraction 21/35. They also give you lists of numbers you can divide 21 and 35 by. By checking these lists, you find out that 21 and 35 can both be divided by 7. So, you divide 21 by 7 and 35 by 7, which gives you 3/5. This means 21/35 simplified is 3/5.

Doing this helps you practice making fractions simpler and understand how odd numbers can be divided.
