Krista wants to paint her house. she buys 7 1/2. gallons of paint. she uses 3/5 of the paint on the front of her house and then buys 1. 1/2. more gallons of paints how many gallons of paint does she have left

Respuesta :

We know that 7 1/2 is equivalent to 15/2.

If she uses 3/5, then it would remain 9/2 gallons.

[tex]\frac{15}{2}\cdot\frac{3}{5}=\frac{9}{2}=4.5[/tex]

Then, she buys 1 1/2, which is equivalent to 1.5 or 3/2.

So, she has 6 gallons of paint.

[tex]4.5+1.5=6[/tex]
