Answer:

i) 4 : 5

ii) 4 : 9

iii) 5 : 9

Step-by-step explanation:

i) weight of copper = 120g

weight of zinc = 150g

ratio = 120/150 = 4/5 =

4 : 5

ii) weight of copper = 120g

total weight of alloy = 120 +150 = 270g

ratio = 120/270 = 4/9 =

4 : 9

iii) weight of zinc= 150g

weight of alloy = 270g

ratio = 150/270 =

5 : 9
