The answer is A. Twenty-five is 65% of what number?
Why? This is due to how if you multiply 'w'(the number) by 0.65(65%) then you get 25. This indicates that whatever the number is, if it is multiplied by 65% it equals 25. Thus concluding that 25 is 65% of the unknown number.
I hope that helps, have a great rest of your day! ^ ^

The above is a simple math problem and the answer to x which is the unknown is -6.5 approximately.
<h3>What is the calculation for the above answer?</h3>
First, lets rewrite the word problem:
-1.96321 and - √(x) = 5
Note that "and" is also multiplication in math.
Hence,
-1.96321 * - √(x) = 5
- √(x) = 5/-1.96321
-x = (5/-1.96321)²
- x = 6.48644131993
x = - 6.48644131993
x
-6.5
