It is common to see mixed fractions in recipes. A recipe for pizza crust may ask for 1 1/2 cups of flour. You could measure this amount in two ways. You could fill a one-cup measuring cup with flour and a one-half cup measuring cup with flour or you could fill a half-cup measuring cup three times, because 1 1/2 is the same as 3/2.
In the following recipes, some mixed numbers have been changed to improper fractions and other fractions may not be written in simplest form. Rewrite each recipe as you would expect to find it in a cookbook.
1.3/2 cups flour
1 1/2 cups off lour
2.2/4 cups of water
1/2 cups of water
3.9/4 teaspoons yeast
2 1/4 teaspoons of yeast
4.2/2 teaspoons salt
1 teaspoon of salt
5.4/4 teaspoon sugar
1 teaspoon of sugar
6.8/8tablespoon oil
1tablespoon of oil
All are right.
7. 4/3 cups sesame seeds
1 1/3 cups of sesame seeds
8.4/2 cups cocounut
2 cups of coconut
9.3/2 cups of sunflower seeds
1 1/2 cups of sunflower seeds
10.8/2 cups rolled oats
4 cups of rolled oats
11.2/2 cups honey
1 cup of honey
12.4/4 tablespoon brown sugar
1 tablespoon of brown sugar
All are right. You're good at this! :-)
3/2 cups white sugar
1 1/2
3/2 cups brown sugar
1 1/2
4/2 cups flour
2 cups
4/2 cups oatmeal
2 cups
8/3 sticks margarine
2 2/3 margarine

Yes!
1. 1 1/2 cups flour
- To rewrite this recipe as you would expect to find it in a cookbook, we can convert the improper fraction 3/2 back to a mixed number. To do this, divide the numerator (3) by the denominator (2):
- 3 ÷ 2 = 1 with a remainder of 1.
- The quotient (1) becomes the whole number part and the remainder (1) becomes the numerator of the fraction part. So, the rewritten recipe would be:
- 1 1/2 cups flour
2. 1/2 cup of water
- The fraction 2/4 is not in its simplest form. To simplify it, we can divide both the numerator and the denominator by their greatest common factor, which is 2:
- 2 ÷ 2 = 1
- 4 ÷ 2 = 2
- After simplifying, the fraction becomes 1/2. So, the rewritten recipe would be:
- 1/2 cup of water
3. 2 1/4 teaspoons of yeast
- The mixed number 9/4 can be converted back to an improper fraction by multiplying the whole number part (2) by the denominator (4) and adding the numerator (1):
- 2 * 4 = 8
- 8 + 1 = 9
- The improper fraction is 9/4. So, the rewritten recipe would be:
- 2 1/4 teaspoons of yeast
4. 1 teaspoon of salt
- The fraction 2/2 is equal to 1 when simplified. So, the rewritten recipe would be:
- 1 teaspoon of salt
5. 1 teaspoon of sugar
- The fraction 4/4 is equal to 1 when simplified. So, the rewritten recipe would be:
- 1 teaspoon of sugar
6. 1 tablespoon of oil
- The fraction 8/8 is equal to 1 when simplified. So, the rewritten recipe would be:
- 1 tablespoon of oil
