Question 586689
If you want to know the answer, here is the formula:

P(Part) = W(Whole) x %(Percent)

Since your missing the whole, divide both sides with percent to let W(Whole) alone.

(P / %) = ([W X %] / %)

then...

P / % = W

So, to find the whole, get the whole by dividing the Part by the Percent.
The solution would be:

98 / 40% = W

then...

98 / .04 = W

The answer would be 2450.

Since 98 / .04 is equal to 9800 / 4. 9800 / 4 is just the simplified form of 98 / .04.

98 / .04 = 980 / .4 = 9800/4
