3.A field of grass was 10cm long.When a lawnmower cut it, it's height dropped by 75mm. How high is it now in centimeters?

PartB!

1.13.5'C is the answer to number 1.We solved this by adding -7'c with 20.5'c, but, in an easier form is 20.5'c subtract 7'c.20.5'c-7'c=13.5'c.

2.The answer for no.2 is £4.We got this answer by £7.99 subtract £3.99.£7.99-£3.99=£4.00.

3.The answer to no.2 is 2.5cm.We got this answer by turning 10cm into 100mm,

subtracting 75mm and turning the answer into centimeters.10cm/10=100mm.100mm-75mm=25mm.25mmX10=2.5cm.
