@@demiking6528 hi this is actually a very good question! We were trying to make 100% from 120%. Dividing 120 by 6 gave us 20 (which goes into 100) and we then multiplied 20 by 5 to get the 100. These were just tactics to get 100 bearing in mind we couldn't use a calculator!

@@ExamSolutions_Maths Ok thanks that makes more sense! Do you offer some 1-1 help for payment? these videos are great but there is nothing like having it explained.
