Good question let me see if I can figure it out
Answer: the denominator represents the number of equal parts in a whole, and the numerator represents how many parts are being considered.
Step-by-step explanation:
7a+21=56
Begin by subtracting 21 on both sides:
21-21=0 so the 21 in the left cancels, then 56-21=35
Your new equation will be
7a=35
Finally, divide by 7 on both sides:
7/7=1 and 35/7=5
your answer will be
a=5
