We can use the percent formula to solve. The percent formula is below: ^part⁄_whole = ^%⁄₁₀₀ We are given the part (3) and the whole (8), and asked to calculate the percent. We don't know the percent, so that is where we will put our variable (x): ^part⁄_whole = ^%⁄₁₀₀ ³⁄₈ = ^x⁄₁₀₀ Cross multiply and solve for x: ³⁄₈ = ^x⁄₁₀₀ 8 * x = 3 * 100 8x = 300 8x/8 = 300/8 x = 37.5 So, 3 is 37.5% of 8.
