Rapid Revision For School Students To calculate one quarter of a number, we divide by 4.

# Fractions (Year 4)

As children progress through KS2 they will learn more about fractions in Maths. As well as understanding the different values of fractions, in Year Four children will be exposed to smaller fractions such as twentieths. They will also learn how to go about calculating fractions of other numbers.

Fractions can be written more than one way. For instance ten twentieths could be written as 1020 and it has the same value as 12 or 24. When you are calculating fractions of numbers you divide them by the number below the line and then times the answer by the number above the line. For example, to work out four twentieths of forty you divide 40 by 20, which is 2, then times two by 4 giving the answer 8.

1.
Which of these fractions is equivalent to 34?
23
610
46
68
6 ÷ 2 = 3 and 8 ÷ 2 = 4 so 34 is the same as 68
2.
What is one tenth of 30?
3
6
10
20
To calculate one tenth we divide by 10
3.
Which fraction is the greatest?
410
56
23
1120
56 is 16 less than 1
4.
Which is the smallest of these fractions?
14
18
120
16
If the numbers above the line are equal then the fraction with the highest number below the line is smaller
5.
Which of these is NOT equivalent to 12?
24
36
23
48
23 is more than 12
6.
Which of these fractions is equivalent to one quarter?
28
13
36
25
One eighth is half of one quarter so two eighths is equivalent to one quarter
7.
How do we calculate one quarter of a number?
Divide by 2
Multiply by 4
Divide by 4
Multiply by 2
16 ÷ 4 = 4 so 14 of 16 is 4
8.
Which fraction is greater than 12?
14
510
26
1120
1020 is equivalent to 12 so 1120 must be more
9.
Which represents one eighth?
14
18
120
15
18 is the same as 1 divided by 8
10.
If we divide a number by 3 the result will be?
14
110
16
13
9 ÷ 3 = 3 so 13 of 9 = 3
