Divide the numerator and denominator by 25. (the greatest common factor)
75/25=3 100/25=4
2. 0.25 of the pizza is remaining. You find this solution by subtracting the amount that was eaten (determined above) by the total. You can then easily turn a percentage into a decimal by adding a "0." behind the percentage.
3. Draw one quarter of a circle for the pizza slice.
The reason is because (as determined above) there is one quarter of the pizza remaining.
