Answer:
False.
Since the number of numbers in the world is infinite, there can be an infinite number of equivalent fractions.
Step-by-step explanation:
15 - c = 6
15 - 6 = c
9 = c
c = 9
There will have to be 5 because of the 4
It's not possible nothing but 1 times 5 is the only thing that multiplies to 5 and 1+5 doesn't equal 4
