Multiplication and Division (Easy)

Multiplication and division can involve dealing with fractions. Knowing your times tables is always useful when it comes to multiplying and dividing. You should be able to do most of this stuff in your head.

Are you a numbers person? Do you like numbers? Many careers involve a solid knowledge of how numbers work. To help you with this 11-plus Maths quiz and our others on multiplication and division, we have a number of times tables quizzes in our 11-plus curriculum. They only go up to the 12 times tables, but if you wanted you could always teach yourself higher tables. If you are a 'numbers nerd', then impress your friends with the 14, 18 or even 23 times table!

This quiz involves multiplying and dividing using fractions which is a little trickier than whole numbers. Make sure you get 10 out of 10 before moving onto our next quiz in the series.

What is the correct answer to the given calculation?
18 × 64
8
16
4
2
Multiplying by 18 is the same as dividing by 8 ∴ 64 ÷ 8 = 8. In general, multiplying by 1 over a number is the same as dividing by that number: in this case, 8

What is the correct answer to the given calculation?
15 × 25
75
125
13
5
15 × 25 = 25 ÷ 5 = 5. In general, multiplying by 1 over a number is the same as dividing by that number: in this case, 5

What is the correct answer to the given calculation?
10,000 × 25
250,000
25,000
2,500
250
10,000 × 25 = 250,000. To multiply 25 by 1,000, just add three zeros to 25. If there is a decimal point in the number, move the decimal point 3 places to the right and add a zero for each place position if there are no digits in those place positions. You should be able to do this in your head
4.
What is the correct answer to the given calculation?
12 ÷ 7 gives a fractional remainder
75
57
712
512
12 ÷ 7 = 1 remainder 5. You are dividing by 7, so the fractional remainder must be 57
5.
What is the correct answer to the given calculation?
17 × 25
342
452
425
354
Short cut: 17 × 25 = (17 × 100) ÷ 4 = 1,700 ÷ 4 = 425. Multiply 25 by 4, then divide the product by 4. Be on the LOOKOUT for products that can be simplified: this will enable you to do the calculation in your head
6.
What is the correct answer to the given calculation?
12 ÷ 27
42
3.4
48
56
To divide by a fraction, invert (turn upside down) the fraction and multiply. LEARN this technique. So, 12 ÷ 27 = 12 × 72 = (12 × 7) ÷ 2 = 84 ÷ 2 = 42

What is the correct answer to the given calculation?
18 ÷ 5 gives a fractional remainder
35
53
518
318
18 ÷ 5 = 3 remainder 3. You are dividing by 5, so the fractional remainder must be 35

What is the correct answer to the given calculation?
The number of 19 in 50
5.6
45
9
450
The number of 19 in 50 = 50 × 9 = 450. To divide by a fraction, invert (turn upside down) the fraction and multiply: in this case, dividing by one ninth is the same as multiplying by 9. LEARN this technique

What is the correct answer to the given calculation?
50 ÷ 2100
1
25,000
25
2,500
50 ÷ 2100 = 50 ÷ 150 = 50 × 50 = 2,500. To divide by a fraction, invert (turn upside down) the fraction and multiply, but DON'T forget to simplify the fraction whenever you can. LEARN this technique
10.
What is the correct answer to the given calculation?
49 × 13
610
601
673
637
