1.	A paper Is 2 metres long. I need 8 pieces of paper each 30 cm long. How many centimetres shorter is the paper than the length I need?
Answer» A piece of 30 cm, so for 8 pieces paper needed is 30 x 8 = 240 cm. But paper is 2 metre = 2 x 100 = 200 cm long. So paper is shorter by 240 – 200 = 40 cm

Answer»

A piece of 30 cm, so for 8 pieces paper needed is 30 x 8 = 240 cm.

But paper is 2 metre = 2 x 100 = 200 cm long.

So paper is shorter by 240 – 200 = 40 cm
