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 full tank capacity (50) Part: the amount of water currently in it (x) Percentage: 31% ^part⁄_whole = ^%⁄₁₀₀ ^x⁄₅₀ = ³¹⁄₁₀₀ Cross multiply and solve for x: ^x⁄₅₀ = ³¹⁄₁₀₀ 100 * x = 31 * 50 100x = 1,550 100x/100 = 1,550/100 x = 15.5 So, 15.5 is 31% of 50.
