The answer

How to turn 17/20 into a decimal
The quick way is to make an equivalent fraction with a bottom of 100, because hundredths can be written straight down as a decimal.
- 20 × 5 = 100.
- Do the same to the top: 17 × 5 = 85.
- So 17/20 = 85/100, which is 85 hundredths.
85 hundredths is written 0.85: the last digit goes in the hundredths column.
You can also divide the top by the bottom. Short division gives the same answer:
- 20 does not go into 17, so write 0 and a decimal point, then carry the 17 over as 170 tenths.
- 20 goes into 170 8 times, remainder 10. Write 8, and carry the 10 to make 100.
- 20 goes into 100 5 times exactly. Write 5.
- The remainder is 0, so the division stops: 17 ÷ 20 = 0.85.
