Question

1) Find x, if 1/3 of x is 14

Answer 1

"of" means multiply      and         "is" means equal

1. $\frac{1}{3}$x = 14

                                x = 14(3)      multiply both sides by 3 to isolate "x"

                                x = 42

2. $\frac{1}{5}$x = 14

                                x = 14(5)      multiply both sides by 5 to isolate "x"

                                x = 70

3. $\frac{2}{5}$x = 14

                                2x = 14(5)      multiply both sides by 5

                                2x = 70

                                  x = 35         divide both sides by 2 to isolate "x"

4. $\frac{7}{8}$x = 14

                                7x = 14(8)      multiply both sides by 8

                                7x = 112

                                  x = 16         divide both sides by 7 to isolate "x"
