. An alloy contains 120g of copper and 150g of 2006
① Find the ratio of copper and zinc.
2.find the ratio of copper and total weight of alloy.
3. Find the ratio of zinc and total weight of alloy.

1. 4:5

2. 4:9

3. 5:9

Step-by-step explanation:

Weight of the alloy= 270g

1. Ratio of copper and zinc= 120:150

= 4:5

2. Ratio of copper and alloy= 120:270

= 4:9

3. Ratio of zinc and alloy= 150:270

= 5:9

i agree because i see the other persons thinking is clear
