5/7 - 3/9 = what is the answer for this problem can u explain how would I get the answer for this problem
1 answer:
Step-by-step explanation:
To solve this problem, we should first have common denominators.
We should find the LCM (Least Common Multiple) of the 2 denominators.
The LCM of 7 and 9 is 63.
Each fraction is out of 63, but whatever number you multiply to get 63, you use that same number for the numerator.
5 x 9 = 45, 3 x 7 = 21.
We have our problem, 45 / 63 - 21 / 63.
Subtract the 2 numerators.
45 - 21 = 24.
Our answer is 24 / 63.
We need to simplify this problem.
Both numbers are divisible by 3.
Divide both Terms, or numbers by 3.
24 / 3 = 8.
63 / 3 = 21.
<u>8 / 21 is our answer simplified.</u>
<u></u>
Therefore, your difference is 8 / 21.
Best of Luck to you.
