First, make sure that there is a common denominator, or in other words, the denominators, are the same.

You have the numbers 15 and 5 and the lowest common multiple between the two is 15, and in order to make sure the denominators are both the same, you multiply 5 by 3.

Now, whatever you do to the bottom, you make sure you do to the top. In other words, multiply the numerator by 3 as well, and the second fraction is now 3/15. You can now subtract 3 from 13 and the answer is 10/15. You can reduce that to 2/3 by factoring out a 5.

13/15 - 1/5 --> 13/15 - 3/15 = 10/15 --> 2/3

Find the missing section. Answers must be in fraction form.

frozen [14]

Answer:

$\frac{1}{10}$

Step-by-step explanation:

We have a circle that is split in three sections, two of which we know and we are asked to find the third missing section.

For the circle, we know that 4/5 and 1/10 is fit. Now we need the last one, to solve, we need to get the same denominator and see how much is missing.

Since 1/10 is our highest denominator, let's change 4/5 to have 10 as a denominator. Which would be through multiplying 5 to get 10.

What times 5 equals 10?

Now multiply both numerator and denominator by 2 to get our portion.

$\frac{4*2}{5*2}$
