A liquid fertilizer is diluted at a rate of 15ml per 10 litres of water. The label claims that 5L of diluted mixture is required per every 10 square metres of lawn. How many ml of fertilizer is needed to fertilize a 120m2 lawn?
120 ÷ 10 = 12 first we find out how many 10 metres squared are in 120 metres squared by dividing
total amount of litres of mixture = 12 × 5
= 60 Litres
so we need 12 lots of 5 Litres
which is 60 Litres of mixture
60 ÷ 10 = 6 each 10 litres of mixture has 15mls of fertilizer in, so we find out how many lots of 10L is in 60L by dividing
6 × 15 = 90ml we need 6 lots of the fertilizer : which is 6 lots of 15ml
