7/20 as 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.

1. 20 × 5 = 100.
2. Do the same to the top: 7 × 5 = 35.
3. So 7/20 = 35/100, which is 35 hundredths.

35 hundredths is written 0.35: the last digit goes in the hundredths column.

You can also divide the top by the bottom. Short division gives the same answer:

1. 20 does not go into 7, so write 0 and a decimal point, then carry the 7 over as 70 tenths.
2. 20 goes into 70 3 times, remainder 10. Write 3, and carry the 10 to make 100.
3. 20 goes into 100 5 times exactly. Write 5.
4. The remainder is 0, so the division stops: 7 ÷ 20 = 0.35.

Every twentieth is 5 hundredths: 7/20 is 7 × 5 = 35 hundredths, which is 0.35.

7/20 sits between 1/3 (0.333...) and 1/2 (0.5). It is closer to 1/3.
