Year 6 equivalent fractions

Here is another page of equivalent fractions. A part of each pair of fractions is missing and the missing numerator or denominator should be entered. Remember, equivalent fractions are fractions that have the same total value.

One interesting way to check whether two groups equivalent is to perform a couple of multiplications; What is known as cross multiplication. To verify that a/b is equal to c/d just multiply a by d, and then (b) multiplying c. If the two answers are equal then the fractions equivalent. This is a really good way to check to see if the answers are correct.

Year 6 maths worksheet: Equivalent fractions

equivalent fractions pg 1

Insight into equivalent fractions is the core of understand how fractions work. Much work needs to be done in previous years to show that fractions such as 1/2 and 2/4 have the same value. This is usually done by colors or shading parts of rectangles, circles.

Two fractions that are equal in value that we say are are equivalent.

2/5 is equal to 4/10 which is equivalent to 40/100.

If we start with a group and both the numerator (top number) as the denominator (bottom number) multiplied by the same number remains the break with the same value. The same goes with Division, but not add or subtract.

This makes multiplying fractions much easier than adding or subtracting from them.
