Answer:
1/2m+ 3/4m- m=2.5
2m+ 3m- 4m/ 4= 2.5
1/4m= 2.5
m= 2.5× 2
m= 10 ans.
10. 3a/ 4 + a/6= 66
9a + 2a/ 12= 66
11/ 12a= 66
a= 66× 12/ 11
a= 72
12. 0.6a + 0.2a = 0.4a+ 8
0.8a - 0.4a = 8
0.4a = 8
a = 20
14. 10/ 100 × x = 20
1/ 10x = 20
x= 20× 10
x= 200
16. x- 30/ 100× x = 35
- 2x = 350
x= 350/ -2
x = -175
Hope it helps..
