            Fantastic Fractions
We are learning to identify the relationship between equivalent fractions.


What is 1/4 of 4? 1

What is ¼ of 8? 2

What is ⅓ of 6? 2

What is 2/6 of 12? 4

What is ¼ of 20 ? 5

What is 1/10 of 20? 2


I have 5/16 of a cake at a birthday party. I keep going back for more and eat another  6/16 of a cake. What fraction of a cake have I eaten altogether?  5/16 + 6/16 = 176/256

I have 10/21 of a cake left over from the party. Then I give 6/21 of a cake to my sisters. What fraction of a cake do I have left over? 90/441


1/2 + 3/4 =  10/8

2/6 + ⅔ = 18/18

⅕ + 2/10 =  20/50

2/6 + 4/12 = 48/72

2/5 + 3/15 = 45/7

1/9 + 1/18 = 26/162

2/9 + 4/18 = 72/162

  1. Hi Mathew,

    Wow! You did really well with this maths work although you made it very difficult for yourself by changing the denominator of each fraction. Remember when the fractions have the same denominator (1/10 + 3/10 = 4/10) you don't need to find a multiple of the denominators. You only do this when they are not equivalent - like 1/3 + 1/2
