Question

Wyatt uses 3/4 gallon to paint 2 identical doghouses. he has 5 1/2 gallons, how many doghouses and how much paint left over

Answer 1

First find out how much paint it takes to paint one doghouse. 

3/4 ÷ 2 = 3/4 * 1/2 = 3/8 gallons of paint for one doghouse. 

 

Now divide the total paint by 3/8

 

5 1/2 ÷ 3/8 = 11/2 * 8/3 = 88/6 = 14 4/6 = 14 2/3. Therefore he has enough paint to paint 14 doghouses. 

 

To find the leftover paint.  Multiply 14 by the amount of paint it takes to paint one. 

14 * 3/8 = 42/8 = 5 2/8 = 5 1/4.  It takes, 5 1/4 gallons of paint to paint 14 doghouses. 

 

The amount leftover is found by subtracting 5 1/2 - 5 1/4 = 11/2 - 21/4 = 22/4 - 21/4 = 1/4.  There will be 1/4 gallon left over.
