Equivalent Fractions One Whole 1
Equivalent Fractions Cut them in half
Equivalent Fractions Shown is one half 1 2 How many pieces we want How many pieces it’s cut into
Equivalent Fractions Shown is one half 1 2 NUMERATOR DENOMINATOR
Equivalent Fractions I cut my shape again I still show 1 2
Equivalent Fractions But I also show 2 4
Equivalent Fractions One half is EQUIVALENT TO 2 quarters 1 2 2 4
Equivalent Fractions 1 2 2 4 This symbol looks like an equals sign with a third line. It is the mathematical sign for EQUIVALENT TO which means “is worth the same as”.
Equivalent Fractions We can use equivalent fraction to make our numbers easier to handle. Smaller numbers are SIMPLE 160 200 ÷ 10 16 20 ÷ 4 4 5
Equivalent Fractions Simplest form We can use different language for making the fraction as small as possible. Lowest terms Watch out for this language in the Simplified future. It is often used in Key Stage 3. Cancelled down 160 4 200 5 This fraction is as simple as we can make it
Equivalent Fractions 15 45 60 80 Look for numbers that both the NUMERATOR and the DENOMINATOR can be divided by. We want numbers bigger than 1. We call these COMMON FACTORS
Equivalent Fractions 15 ÷ 3 45 ÷ 3 60 ÷ 10 80 ÷ 10 These numbers have 3 as a common factor. This means they can both be shared by 3. A common factor here is 10
Equivalent Fractions 15 ÷ 3 5 45 ÷ 3 15 60 ÷ 10 6 80 ÷ 10 8
Equivalent Fractions 15 ÷ 3 5 ÷ 5 45 ÷ 3 15 ÷ 5 60 ÷ 10 6 ÷ 2 80 ÷ 10 8 ÷ 2
Equivalent Fractions 15 ÷ 3 5 ÷ 5 1 45 ÷ 3 15 ÷ 5 3 60 ÷ 10 6 ÷ 2 3 80 ÷ 10 8 ÷ 2 4
Equivalent Fractions 15 1 45 3 60 3 80 4 If the top number is a 1, we know we can stop. If the top and bottom number are not DIVISIBLE by the same number, we stop.
