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>
