Answer:

Step-by-step explanation

As we know

ratio of zinc and copper in the alloy =7:9

and the weight of alloy is =8kg

so,the weight of copper in the alloy is as follow

7+9=16

we have to find copper weight so we will take copper ratio

9/16=8=9/2

=4.5kg

and the weight of zinc is 7/16=8=7/2

3.5kg

4.5+3.5=8kg
