Question

How do you change 0.50 into a fraction?

Answer 1

A decimal is the result of performing the division indicated by a fraction.
`5/10` or `1/2`

Explanation:

To reverse that process, we can set up the equation:

`A/B = 0.ZZZ`

We have the final result, `0.50`. for simplicity we will want it "normalized", or equivalent to something out of `"1"` or `100`. I like to start with a denominator of 100 because it relates directly to percentages, and it can always be simplified if desired.

`A/100 = 0.50` This means, What is the value of A in parts per hundred that is equal to 0.50?

Solving for "A": `A = 0.50 xx 100 = 50`

Therefore the original ratio or fraction equivalent is:
`50/100` as mentioned, this can also be reduced to a smaller ratio, if desired: `5/10`, or even `1/2`.

Both fractions are equivalent to the decimal value `0.50`.
