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 original goal (78) Part: the number of books read so far (x) Percentage: 83.33% ^part⁄_whole = ^%⁄₁₀₀ ^x⁄₇₈ = ^83.33⁄₁₀₀ Cross multiply and solve for x: ^x⁄₇₈ = ^83.33⁄₁₀₀ 100 * x = 78 * 83.33 100x = 6,500 100x/100 = 6,500/100 x = 65 So, 65 is 83.33% of 78.
