Welcome to the third in our series of Very Easy Eleven Plus maths quizzes on Multiplication and Division. These can be testing at times – especially when dealing with large numbers. They often require pencils and paper for you to do your calculations but, you’ll be happy to hear, there are some simple ways to work many of them out.

Here’s an example: if you are asked to multiply a number by 95, then all you have to do is multiply it by 100, then multiply it by 5, and finally subtract the smaller number from the larger one:

8 x 95 = (8 x 100) - (8 x 5) = 800 - 40 = 760

See how easy it is when you can simplify the calculation. Read the helpful comments after each question for more tips which will help you revise for your exams. Good luck!

1.

What is the correct answer to the given calculation?

57,000 ÷ 3,000

57,000 ÷ 3,000

18

19

20

21

To quickly divide by 3,000, first divide by 1,000, then divide your answer by 3:
57,000 ÷ 1,000 = 57, then 57 ÷ 3 = 19

2.

What is the correct answer to the given calculation?

2,000 x 7.5

2,000 x 7.5

12,000

15,000

18,000

21,000

To multiply by 2,000, simply multiply by 2 then by 1,000 by adding 3 zeros:

2 x 7.5 = 15, then 15 x 1,000 = 15,000

2 x 7.5 = 15, then 15 x 1,000 = 15,000

3.

What is the correct answer to the given calculation?

1,080 ÷ 200

1,080 ÷ 200

4.5

5.4

45

55

To divide by 200, first divide by 100 by moving the decimal point 2 places to the left, then divide by 2:

1,080 ÷ 100 = 10.8, then 10.8 ÷ 2 = 5.4

1,080 ÷ 100 = 10.8, then 10.8 ÷ 2 = 5.4

4.

What is the correct answer to the given calculation?

425 ÷ 5

425 ÷ 5

85

75

65

55

To quickly divide by 5, first divide by 10 then double your answer:
425 ÷ 10 = 42.5, then 42.5 x 2 = 85

5.

What is the correct answer to the given calculation?

64 quartered

64 quartered

4

32

16

8

‘Quartered’ means divided by 4: 64 ÷ 4 = 16

6.

What is the correct answer to the given calculation?

90 x 300

90 x 300

2,700,000

270,000

2,700

27,000

To multiply by 300, first multiply by three, then by 100:
90 x 3 = 270, then 270 x 100 = 27,000. Alternatively, if both numbers end with zeroes, these can be removed and added again at the end:

9 x 3 = 27. We removed 3 zeros, so we add them again to get 27,000

9 x 3 = 27. We removed 3 zeros, so we add them again to get 27,000

7.

What is the correct answer to the given calculation?

3 cubed

3 cubed

27

9

15

12

‘Cubed’ means multiplied by itself twice, just like finding the volume of a cube: vol = b x h x w.

3 x 3 x 3 = 27

3 x 3 x 3 = 27

8.

What is the correct answer to the given calculation?

12 x 40

12 x 40

240

360

480

600

To multiply by 40, first multiply by 4 then by 10:
12 x 4 = 48, then 48 x 10 = 480

9.

What is the correct answer to the given calculation?

6 doubled then squared

6 doubled then squared

12

36

48

144

'Double' means multiply by 2, and ‘squared’ means multiplied by itself:

6 x 2 = 12, then 12 x 12 = 144

6 x 2 = 12, then 12 x 12 = 144

10.

What is the correct answer to the given calculation?

93 x 101

93 x 101

9,193

9,293

9,393

9,483

A quick way to multiply by 101 is to first multiply by 100, then add the original number:
93 x 100 = 9,300, then 9,300 + 93 = 9,393
