1.
Your mum made 132 cupcakes and sold 89 at the bake sale. How many cupcakes are left?
33
43
53
63
Subtract 89 cupcakes from the original 132 to find out how many are left. 132 - 89 = 43.
2.
Add 12,345 to 6,754. What do you get?
17,999
18,999
19,099
19,199
Adding 12,345 and 6,754 equals to 19,099. If you get confused, add the columns starting from the right; units, tens, hundreds and so on.
3.
A biscuit weighs 85g, how much will 9 biscuits weigh?
750g
765g
775g
850g
One biscuit weighs 85g. Therefore, 9 biscuits will weigh 9 x 85g = 765g.
4.
From the number 3,659, subtract 1,832. What number is left?
1,826
1,827
1,828
1,829
If you subtract 1832 from 3659, you get 1,827.
5.
There are 800 students in a school. 350 are girls. How many boys are in the school?
350
400
450
500
If you subtract the number of girls (350) from the total number of students (800), you will get the number of boys, which is 450.
6.
A sack of rice weighs 16kg. If you split it equally into 4 parts, how much does each part weigh in kg?
1kg
2kg
3kg
4kg
When the 16kg is split into 4 equal parts, each part will weigh 16kg ÷ 4 = 4kg.
7.
If a toy car costs £8.50 and you have only £5. How much more money do you need to buy the toy car?
£2.50
£3.00
£3.50
£4.00
To find the amount needed, subtract the money you already have (£5) from the cost of the toy car (£8.50). The resulting difference, £3.50, is the amount you need more.
8.
If you had £3.25 and you spent £1.75, how much money have you got left?
£1.00
£1.25
£1.50
£1.75
Subtraction is the key here. Subtract £1.75 from £3.25 and you are left with £1.50.
9.
What is the sum of 47 and 53?
90
100
110
120
Adding 47 and 53 equals 100. If you're not sure, break it down. For example, add the tens first (40 + 50 = 90) then add the units (7 + 3 = 10). Finally, add these two together (90 + 10 = 100).
10.
If you had a 2 litre bottle of water and you poured out 750ml, how much water would be left in litres?
1 litre
1.25 litres
1.5 litres
2 litres
Think that each 1,000ml is equal to 1 litre. So, 750ml is 0.75 litres. Therefore, 2 (whole litres) minus 0.75 (750ml in litres) leaves you with 1.25 litres.
