We can use the percent formula to solve. The percent formula is below: ^part⁄_whole = ^%⁄₁₀₀ Based on the text, these are the values we will plug into the percent formula to solve: Whole: the total number of slices (25 * 8 = 200) Part: the number of slices eaten (x) ^part⁄_whole = ^%⁄₁₀₀ ^x⁄₂₀₀ = ⁷⁰⁄₁₀₀ Cross multiply and solve for x: ^x⁄₂₀₀ = ⁷⁰⁄₁₀₀ 100 * x = 200 * 70 100x = 14,000 100x/100 = 14,000/100 x = 140 So, 140 is 70% of 200.
