**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.

To divide by a fraction, invert (turn upside down) the fraction and multiply. LEARN this technique. So, 12 ÷ ^{2}?_{7} = 12 × ^{7}?_{2} = (12 × 7) ÷ 2 = 84 ÷ 2 = 42

17 × 25

17 × 25

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

4 .

What is the correct answer to the given calculation?

^{1}⁄_{5} × 25

5 .

What is the correct answer to the given calculation?

10,000 × 25

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

6 .

What is the correct answer to the given calculation?

49 × 13

49 × 13

610

601

673

637

49 × 13 = (50 × 13) - 13 = 637. Increase 49 by 1 and do the multiplication THEN subtract 13. Be on the LOOKOUT for products that can be simplified: this will enable you to do the calculation in your head

7 .

What is the correct answer to the given calculation?

50 ÷^{2}⁄_{100}

50 ÷

1

25,000

25

2,500

50 ÷ ^{2}?_{100} = 50 ÷ ^{1}?_{50} = 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

8 .

What is the correct answer to the given calculation?

The number of^{1}⁄_{9} in 50

The number of

5.6

45

9

450

The number of ^{1}?_{9} 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

9 .

What is the correct answer to the given calculation?

12 ÷ 7 gives a fractional remainder

12 ÷ 7 gives a fractional remainder

12 ÷ 7 = 1 remainder 5. You are dividing by 7, so the fractional remainder must be ^{5}?_{7}

10 .

What is the correct answer to the given calculation?

18 ÷ 5 gives a fractional remainder

18 ÷ 5 gives a fractional remainder

18 ÷ 5 = 3 remainder 3. You are dividing by 5, so the fractional remainder must be ^{3}?_{5}
