Subtract the fractions and simplify the answers 13/15-1/5

The answer to that question is 2/3. In order to get 2/3, you need to let your denominators have the same number. Since you have 15 and 5 as your denominators, you need to multiply 5 by 3 to make it 15 and multiply the numerator 1 by 3 to make it 3. Once you are done, you can now proceed with subtracting since you now have the same denominators. When you are done subtracting, you can then simplify the answer. To put this simply, here is a computation: 

Multiply 1/5 by 3 to make it 3/15 to make the denominators equal.

 13/15 - 1/5=

When you are done multiplying, you’ll get this.

  13/15 - 3/15=

You can now proceed with subtracting and simplifying.

 13/15 - 3/15= 10/15 = 2/3  

The answer would be 27 because assuming that each package has 1 bar of soap and 1 tube of toothpaste, after 27 packages they would run out of toothpaste
