5/8 = 0.625
6 / 9.6 = 0.625
12.8 * 0.625 = 8
x = 8
5.2+4.8= 10
So it has to be 20 I think
The unit rate at which Martin paints in walls per gallon is 1 7/25 walls per gallon
<h3>Unit rate</h3>
Unit rate of paint per gallon = Quantity of wall / gallon of paint

= 4/5 × 8/5
= (4 × 8) / (5 × 5)
= 32/25
= 1 7/25 walls per gallon
