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
