Starter questions

Learning Objective

Revision:

Find percentages of numbers.


Starter questions

Finding Percentages of Numbers

This box represents 40

30% of 40

100% = 40

90% = 36

80% = 32

  • Find 10% first. This can be done by dividing the number by 10

  • 10% of 40 = 4

  • 2) If 10% = 4, then 30% = 12 (there are 3 lots of 10% in 30%)

70% = 28

60% = 24

50% = 20

40% = 16

30% =12

20% = 8

10% = 4

30% of 40 = 12


Starter questions

Finding Percentages of Numbers

Find 10% first

Multiply this by how many lots of 10% there are

Answer

30% of 60

18

60 ÷ 10 = 6

6 x 3 = 18

60% of 20

12

20 ÷ 10 = 2

2 x 6 = 12

20% of 200

40

200 ÷ 10 = 20

20 x 2 = 40

  • Remember:

  • To find 10%, first divide the whole number by 10.


Starter questions

Finding Smaller Percentages of Numbers

This box represents 300. Each square is worth 1%

6% of 300

  • Find 1% first. This can be done by dividing the number by 100

  • 1% of 300 = 3

  • 2) If 1% = 3, then 6% = 18 (there are 6 lots of 1% in 6%)

6% of 300 = 18


Starter questions

Finding Percentages of Numbers

Find 1% first

Multiply this by how many lots of 1% there are

Answer

6% of 400

24

400 ÷ 100 = 4

4 x 6 = 24

15% of 80

12

0.8 x 15 = 12

80 ÷ 100 = 0.8

7% of 500

35

500 ÷ 100 = 5

5 x 7 = 35

  • Remember:

  • To find 1%, first divide the whole number by 100.
