Question

How do you write 0.4% as a fraction?

Answer 1

"Percent" or "%" means "out of 100" or "per 100", Therefore 0.4% can be written as:

`0.4/100`

Or, if we multiply by the numerator and denominator by `10/10` which is the same as multiplying by `1` we obtain:

`0.4/100 xx 10/10 = 4/1000`

Or, we can factor to get:

`4/1000 = (2 xx 2)/(2 xx 2 xx 250) = cancel(2 xx 2)/(cancel(2 xx 2) xx 250) = 1/250`

The solution is: `0.4/100` or `4/1000` or `1/250`
