Number a is 250% of number b. What percentage is the number b of the number a?

Since the number a is 2.5 times greater than the number b, then b = 250: 2.5 = 100%
Thus, we find how many times the number b is less than the number a:
b: a = 100%: 250% = 0.25 times
Therefore, the number b is 0.25 of the number a
We translate into percent and get that the number b is 25% of the number a
