Using the percentage writing form, we know that Ivan ate 4 pizza slices.
By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage.
The percentage calculation formula is (value/total value)100%.
Add all percentages as numbered values, divide by the total number of sets, and you get the average percentage.
The results by 100.
So, we know that:
Ivan ate 40% of the pizza.
And the pizza was cut into 10 slices.
Rewrite the percentage value as:
4/100 = 0.4
We can calculate how many slices Ivan consumed by multiplying the percentage value by the number of slices:
10 + 0.4 = 4
Hence, Ivan ate 4 slices of pizza.
Therefore, using the percentage writing form, we know that Ivan ate 4 pizza slices.
