How to turn 2/5 into a decimal
Divide the top number by the bottom one: 2 ÷ 5. 5 does not go into 2, so write 0 and a decimal point, put a 0 after the 2 and divide:
- 20 ÷ 5 = 4, remainder 0 (4 × 5 = 20). Remainder 0, so the division ends: 2/5 = 0.4
To read it as a percentage, move the decimal point two places to the right: 40%.
