To find how many fifths are in 4.8:
First, we need to become 4.8 into a fraction of a denominator of 5.
So we have 4 + 0.8
Convert 4 into fraction 4 = 4/1
Convert 0.8 into fraction 0.8 = 8/10
Now divide them by 1/5
4/1 ÷ 1/5 = 4/1 * 5/1 = 20/1 = 20
8/10 ÷ 1/5 = 8/10 * 5/1 = 40/10 = 4
So 4+0.8 = 4.8 has 20+4 = 24 fifths
