2. (a) 5/9 X p = 150
5/9 X 270 = 150
(b) 12/p X210 = 360
12/7 X210 = 360
3. (a) 1/2 ton = 500 kg
1 kuintal = 100 kg
1/2 ton = 5 kuintal
(b) 7/5 ton X 1000 kg = 700 kg
1000 - 700 = 300 kg
(c) 1 ton = 1000 kg
2 1/2 = 2,5 X 1000 = 2500 kg
(d) 1 kg = 10 ons
4 X 10 = 40 ons
3/5 X 10 = 6 ons
40 + 6 = 46 ons
