• SOLVING
3m - 1/5 - m/7 = 3
3m - m/7 = 3 + 1/5
( 21m - m ) / 7 = ( 15 + 1 ) / 5
20m / 7 = 16 / 5
20m x 5 = 16 x 7
100m = 112
m = 112/100
m = 1.12
• CHECKING
20m / 7 = 16 / 5
20 x 1.12 / 7 = 16 / 5
22.4/7 = 16/5
3.2 = 3.2
Hence checked

3m-1/5-m/7=3
3m-m/7=3+1/5
(21m-m)/7=(15+1)/5
20m/7=16/5
20m×5=16×7
100m=112
m=112/100
m=1.12
