There are 24 hours in a day and scientists tell us that we should sleep for 3/8 of the day. How much time should we spend sleeping?
= ⅜ of 24 = 9
= 24 ÷ 8 x 3 = 8 ÷ 24 = 3 x 3 = 9
The National History Museum has collected 75 dinosaurs. George has collected 3/5 of this amount. How many dinosaurs has George collected?
= ⅗ of 75 = 45
= 75 ÷ 5 x 3 = 75 ÷ 5 = 15 x 3 = 45
Mr Murrin is 96cm tall and his brother Tom is 7/8 as tall as him. How tall is Tom?
= ⅞ of 96 = 84
= 96 ÷ 8 x 7 = 96 ÷ 8 = 12 x 7 = 84
The weather forecaster says that it is 200 C in London but only 7/10 as hot in New York. How hot is it in New York?
= 7/10 of 200 = 140
= 200 ÷ 10 x 7 = 200 ÷ 10 = 20 x 7 = 140
Skateboards cost $36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?
= 7/9 of 36 = 28
= 36 ÷ 9 x 7 = 36 ÷ 9 = 4 x 7 = 28

I am really impressed with with your answers. I have also had sums similar to yours, but quite more harder to challenge myself. Would you like to challenge yourself?
