Answer:

0

Step-by-step explanation:

<u>Step 1:  Make common denominators</u>

What is the LCM of 21 and 7:  7

So, we need to convert both fractions into a 21 denominator.

<em>15/21 * 1/1 = 15/21</em>

<em>5/7 * 3/3 = 15/21</em>

<em />

<u>Step 2:  Subtract the numbers</u>

15/21 - 5/7 is same as 15/21 - 15/21

15/21 - 15/21

<em>0</em>

<em />

Answer:  0
