Fractions into decimals into %:

⅖ = 2 ÷ 5 = 0.40 = 40% (Move the decimal point 2 places) 3/8 = 3 ÷ 8 = 0.375 = 37.5%

10% of £50 = £50 ÷ 10 = £5 Therefore 40% is 4 x 10% = 4 x £5 = £20 With a calculator: 40% = 0.4 (move the decimal point 2 places to the left)

£50 x 0.4 = £20

0.2

Alternative method: 10% = 999.99 20% = 999.99 x 2 = 1,999.98
