EQUIVALENT FRACTIONS Shade in the second circle so it is equal to the first one. Then fill in the numerator of the fraction next to the second circle and on the next line of the problem.
You can’t always use drawings to find the equivalent fractions. There is a quicker and easier way. Find the number that is multiplied by the old denominator to get the new denominator; then multiply the old denominator by the same number. Solve the problems below. You will be finding equivalent fractions. An example has been done for you. Study it before you do the problems. Example. 2 3
= __ 6
6 7
= __ 14
8 9
= __ 27
4 5
= __ 10

SIMPLIFYING FRACTIONS Reducing numbers to their lowest term is a way of making them easier to understand. To reduce a fraction, find the largest number that will divide evenly into the top and bottom. To reduce a fraction, find the largest number that will divide evenly into the top and bottom, and then write the answers as the reduced fraction. Example: 6 = ______ the highest common factor of 6 and 12 is 6. 12
