Question

By what number must you multiply each side of the equation 2/3x=10 to produce the equivalent equation x = 15?

Answer 1

is it \[\frac23 x=10?\]

Answer 2

in order to get rid of the fraction 2/3 you must multiply both sides by the reciprocal which is 3/2.
sooo.... (3/2)(2/3)x=(3/2)10
the left side will equal 1x and then the right side is 30/2, which is 15
so x=15
