Question

How do you convert 7/9 into a decimal and percent?

Answer 1

`7/9 = 0.bar7 ~~ 0.778`

`7/9 = 77 7/9% ~~ 77.78%`

Explanation:

`7/9` is one of the awkward fractions which do not give an exact decimal, it recurs.

You have to find the decimal by dividing: `7 div 9`

`9|ul7.0000`
`" "0.77777..." "larr` the 7 recurs.

You can write this as `0.bar7" or " 0.dot7`

Or show it to a required number of decimal places - usually 2 or 3.

`7/9 ~~ 0.778`

The decimal gives you the percent immediately because the first 2 decimal places represent hundredths.

`7/9 ~~ 77.78%`

This could also be given as `77 7/9%`
