Bond SATs Skills Arithmetic 10–11

Division Helpful Hint Sometimes a number can’t be divided exactly and there is an amount left over.

This is known as the remainder (r).

Remainders can be written as fractions.

The remainder is the top number (numerator) of the fraction. The number you are dividing by is the bottom number (denominator).

Example: 170 ÷ 6 = 28 r 2 or as a fraction 28 6 or as a simplified fraction 28 3

Answer these questions. You do not need to show your workings out.

Write any remainders as fractions in their simplest form.

Helpful Hint Long division is a way of dividing by bigger numbers. This is because you are unlikely to know the times tables for numbers more than 12. You have to show your workings in a different way. Use multiplication to find the multiples of larger numbers and subtraction to find the remainders. Set your work out in columns.

Example of long division: 56 r2 18 1 0 1 0 –90 110 –108 2

Step 1 18 doesn’t go into 1, so look at the next digit (0). 18 doesn’t go into 10, so look at the next digit (1).

Step 2 18 goes into 101 five times (18 × 5 = 90). To find the remainder, subtract 90 from 101. 101 – 90 = 11 Step 3 Next, bring the 0 down to make 110. 18 goes into 110 six times (18 × 6 = 108). Find the remainder: 110 – 108 = 2 2

So 1010 ÷ 18 = 56 r 2 or 56 18 or 56 9 . It shows 1010 shared equally between 18 groups gives 56 in each group with 2 left over.
