How to solve (1/7) m - (4/7) = 3

There is a couple ways to solve this ... with fractions or without fractions

(without fractions)

1/7m - 4/7 = 3 ... multiply everything by common denominator of 7

m - 4 = 21

m = 21 + 4

m = 25

(with fractions)

1/7m - 4/7 = 3

1/7m = 3 + 4/7

1/7m = 21/7 + 4/7

1/7m = 25/7

m = 25/7 * 7

m = 25

either way, u will get the same answer
