Answer: 0.8
Explanation:
What you need to solve: ?/1=4/5
Since we know that one denominator is 1 and the other is 5, lets make the question mark “x”
x/1=4/5
to convert into the same fraction, x/1=5x/5.
And since the denominators are the same now, that means the numerators are the same. Therefore,
5x=4
x=4/5 (0.8)
