How do you write `17/20` as a decimal?

Answer 1

Multiply numerator denominator with `5` hence

`[17*5]/[20*5]=85/100=0.85`

Remember this is also the same as `85%`

Answer 3

`0.85`

Explanation:

`17/20=17-:20`

`color(white)(aaaaaa)` `color(red)0.85`
`color(white)(aaaaaa)` `-----`
`color(white)(aaaa)20` `|` `17.00`
`color(white)(aaaaaaa)` `160`
`color(white)(aaaaaaa)` `--`
`color(white)(aaaaaaaa)` `100`
`color(white)(aaaaaaaa)` `100`
`color(white)(aaaaaaaa)` `--`
`color(white)(aaaaaaaaa)` `0`

check:

`0.85 xx 20=17`
