The number of pieces of pizza Ivan ate is required.
Ivan ate 4 pieces of pizza.
The number of pizza pieces is \(10\).
The amount of pizza Ivan at is \(40\%\)
The percentage value can also be written as
\(\dfrac{4}{100}=0.4\)
The product of the percentage value and the number of slices will give us the number of slices Ivan ate.
\(10\times 0.4=4\)
