For instance, 1/2 is smaller than 2/3, so you will do 2/3 - 1/2

A recipe needs 3/4 teaspoon black pepper and 1/4 teaspoon red pepper. How much more black pepper does the recipe need?

This fraction word problem requires subtraction.

The fact that the problem is asking how much more black pepper the recipe needs is an indication that 3/4 is bigger than 1/4.

However, it does not hurt to check!

3/4 - 1/4 = 2/4 = 1/2

The black pepper is 1/2 of a teaspoon more than the red pepper.

A football player advances 2/3 of a yard. A second player in the same team advances 5/4 of a yard. How much more yard did the second player advance?

Again, we need to perform subtraction to solve this problem.

5/4 - 2/3 = 15/12 - 8/12 = 7/12

6/12 is equal to 1/2, so 7/12 is just a bit more than half.

So, the second player advanced by about half of a yard more.

To be more precise though, you can say that the second player advanced by 7/12 of a yard more than the first player.

John lives 3/8 mile from the Museum of Science. Sylvia leaves 1/4 mile from the Museum of Science. How much closer is Sylvia from the museum?

The fact that the word problem is saying how much closer Sylvia is, is an indication that 1/4 is smaller than 3/8.

3/8 - 1/4 = 3/8 - 2/8 = 1/8

Sylvia is closer to the library by 1/8 mile.

You can also say that John is further away by 1/8 mile.

Maria caught shrimp that weighted 4 2/3 pounds. If she gave 3 1/6 pounds to his friends, how much shrimp did she have left?

In order to find out how much shrimp Maria is left with, we need to do the following subtraction.

4 2/3 - 3 1/6

4 2/3 - 3 1/6 = (4 - 3) + (2/3 - 1/6)

4 2/3 - 3 1/6 = 1 + (4/6 - 1/6)

4 2/3 - 3 1/6 = 1 + (3/6)

4 2/3 - 3 1/6 = 1 3/6 = 1 1/2

Maria has 1 1/2 pounds of shrimp left.
