➗✖Maths - Decimal/Percentages➖➕

E.g. 
¼ = 4 pieces = 100 divided by 4 is 25. So 0.25… which as a percentage is 25%
⅛ = 8 pieces = 100 divided by 8 is 12.5 .. so as a percentage 12.5%

When there is a numerator larger than one, take your percentage and multiply it by the numerator. 
E.g. 3/5 = 5 pieces = 100 divided by 5 is 20. So ⅕ is 0.20 (or 20%)... 3x20=60, so ⅗ = 0.60 (or 60%)

*Remember to check your place value*

Convert from fraction to decimal then to percentage.
