This may sound kinda weird but I will explain the entire thing along the way:
1. Divide percentage by the amount of sheep
64 / 16 = 4
This means that 4 sheep represent 1% of the flock. When doing this, I can simply use the factor that for each 1% I will calculate, I need to account for 4 sheep.
2. Find the percentage amount that is missing
100 - 16 = 84
This means that 16% of the flock has already been accounted for, and that I need to calculate the final 84%.
3. Multiply the results of step 1 by the percentage needing to be calculated
84 x 4 = 336
This means, that the other 84% of the flock combine for a total of 336 sheep.
4. Add up the percentages and amount of sheep together
16% + 84% = 100%
64 + 336 = 400
This means, that there are 400 sheep in the entire flock.
