**Multiplication and division is multiplying** and dividing numbers. In this 11-plus Maths quiz, you'll learn a few techniques that will help you multiply and divide numbers more easily. Learn as many of these techniques as you think may be useful to you. Knowing your times tables is always useful when it comes to multiplying and dividing.

These questions are longer than usual as they have an extra tip added to them. You might have your own way of doing things, but if you learn the tips, it could improve your maths and make you twice as fast! Being able to calculate quickly isn't just for show; it comes in handy when you are out & about and haven't got the time or a pencil & paper to hand.

Take your time and if you want extra practise, try out some of the tips with other numbers too.

1.

Using the tip, what is the correct answer to the given calculation?

TIP: To multiply a number by 5: first divide by 2, then move the digits to the left. Note: whole numbers that do not have decimal parts are written without a d.p. e.g. 200.0 = 200: in such cases the d.p. is not normally needed.

3,434 × 5 = ?

TIP: To multiply a number by 5: first divide by 2, then move the digits to the left. Note: whole numbers that do not have decimal parts are written without a d.p. e.g. 200.0 = 200: in such cases the d.p. is not normally needed.

3,434 × 5 = ?

17,107

17,017

17,710

17,170

3,434 × 5 = (3,434 ÷ 2) = 1,717. Move the d.p. 1 place to the right gives 17,170. TIP: All odd numbers multiplied by 5 end in 5, and all even numbers multiplied by 5 end in 0

2.

Using the tip, what is the correct answer to the given calculation?

TIP: To divide a number by 5: first multiply by 2 and then move the digits to the right.

888 ÷ 5 = ?

888 ÷ 5 = ?

17,760

17.76

1,776

177.6

888 ÷ 5 = (888 × 2) = 1,776. Move the d.p. 1 place to the left gives 177.6

3.

Using the tip, what is the correct answer to the given calculation?

TIP: To multiply a number by 9: first multiply the number by 10, then subtract the original number from it.

47 × 9 = ?

TIP: To multiply a number by 9: first multiply the number by 10, then subtract the original number from it.

47 × 9 = ?

432

423

324

47 × 9 = (47 × 10) - 47 = 423

4.

Using the tip, what is the correct answer to the given calculation?

TIP: To multiply a number by 11, first multiply the number by 10, then add the original number to it.

96 × 11 = ?

TIP: To multiply a number by 11, first multiply the number by 10, then add the original number to it.

96 × 11 = ?

1,605

1,056

1,560

1,065

96 × 11 = (96 × 10) + 96 = 1,056

5.

Using the tip, what is the correct answer to the given calculation?

TIP: To multiply a number by 8: multiply the number by 2, then by 2 again, and finally by 2.

120 × 8 = ?

TIP: To multiply a number by 8: multiply the number by 2, then by 2 again, and finally by 2.

120 × 8 = ?

609

906

960

690

120 × 2 = 240; 240 × 2 = 480; 480 × 2 = 960

6.

Using the tip, what is the correct answer to the given calculation?

TIP: To divide a number by another number which is a multiple of 10 and whose only non zero digit is the leading digit 1: move the digits to the right by the same number of zeros that are in the multiple of 10. Note: whole numbers that do not have decimal parts are written without a d.p. e.g. 200.0 = 200: in such cases the d.p. is not normally needed.

76,345 ÷ 1,000 = ?

TIP: To divide a number by another number which is a multiple of 10 and whose only non zero digit is the leading digit 1: move the digits to the right by the same number of zeros that are in the multiple of 10. Note: whole numbers that do not have decimal parts are written without a d.p. e.g. 200.0 = 200: in such cases the d.p. is not normally needed.

76,345 ÷ 1,000 = ?

76.345

763.45

7,634.5

0.76345

76,345 = 76,345.0 so 76,345.0 ÷ 1,000 = 76.345: you have to put in the zero to show that there is no whole number part
