45 - 3 = 42
42 ÷ 2 = 21

Two pieces of string are 10cm long and three pieces of string are 6cm long. What is the total length?

[ ]	18cm

10 x 2 = 20 and 6 x 3 = 18
20 + 18 = 38

Six wooden bricks weigh 600g. What do 2 bricks weigh?

[ ]	100g
[x]	200g
[ ]	250g
[ ]	300g

To calculate you need to find how much one brick weighs so 600g ÷ 6 = 100g, so 2 bricks weigh 200g

There are three glasses of water containing 350ml, 250ml and 400ml. When pouring the water into a bowl, half of it is spilt. How much water is left?

[ ]	400ml
[ ]	450ml
[x]	500ml
[ ]	550ml

To solve this problem you need to add 350ml + 250ml + 400ml = 1,000ml. Half of 1,000ml is 500ml

10.

Richard went jogging at 3:30. He jogged for 30 minutes, walked for 10 minutes then jogged again. He arrived home at 4:20. How long was his second jog?

[x]	10 minutes
[ ]	15 minutes
[ ]	20 minutes
