Sam's dog eats 1 1/2 cups of dog food a day. if the scoop holds 1/4 cup of dog food, how many scoops does it take to feed sam's dog?

First, you must convert 1 1/2 into fourths.

To do this, first make it an improper fraction.

1 = 2/2

1/2 + 2/2 = 3/2

Now multiply both the numerator and denominator by 2 to get an equivalent fraction in the form of fourths.

3 • 2 = 6

2 • 2 = 4

3/2 = 6/4

So Sam's dog eats 6/4 cups of dog food each day.

If 1 scoop is 1/4 of a cup, divide how much the dog eats by how much is in each scoop to get the answer.

6/4 : 1/4 = 6

Sam's dog eats 6 scoops of dog food per day.
