Percent Exercises

Answers

  1. x = 0.05 \cdot 30
    x = 7.5

  2. x = 0.38 \cdot 56
    x = 21.28

  3. x \cdot 62 = 50
    \frac{62x}{62} = \frac{50}{62}
    x = 0.806 = 80.6\%

  4. \frac{5}{7} = x \cdot \frac{11}{12}
    (\frac{12}{11}) (\frac{5}{7}) = (x)(\frac{11}{12}) (\frac{12}{11})
    Multiply both sides by the reciprocal of \frac{11}{12}
    \frac{60}{77} = x
    0.779 = x
    77.9\% = x
