Answer:
62
Step-by-step explanation:
50% is technically 1/2 right?
So, if 31 is half of this mysterious number then we just need to times 31 by 2.
Therefore, 31 * 2 = 62.
We can check this by multiplying 62 by .50 (remember that when using percents in an operation we move the decimal over twice)
62 * .50 = 31
I hope this helps!!
