50% of 120 = 60 = 6 5% of 120 60 + 6 = = 66 66 Barnwell School Maths Department S Farquharson
55% of 120 = 66 120 – 66 = 54 buckets (45%) For them both to be 50%, they have to have equal amounts of buckets Take 6 from the concrete and put it onto sand, they both have 60 buckets So it is 6 extra buckets 6 Or, you need 5% more of sand 5% of 120 = 6 Barnwell School Maths Department S Farquharson
