Answer:
<em>2 gallons </em>
Step-by-step explanation:
If Han used 1 1/2 gallons of paint to paint 3/5 of a shed, this can be expressed as;
1 1/2 gallons = 3/5 of the shed
3/2gallons = 3/5 of the shed
To find the number of gallons that will paint the whole shed, we will say;
x gallons = 1 shed
Divide both expressions
3/2/x = 3/5
3/2x = 3/4
2x * 3 = 3*4
6x = 12
x = 12/6
x = 2
<em>Hence 2 gallons will be needed for the whole shed</em>
