Question

the ratio of zinc and copper in an alloy is 7:9 if the weight if coper in the alloy is 12 .6 kg find the weight of zinc in it
​

Answer 1

Answer:

Let the weights be 7x and 9x

So, 9x= 12.6

= X= 12.6/9

= X= 1.4

Therefore, 7x= 7× 1.4

= 9.8

Step-by-step explanation:

So, the weights of zinc is 9.8 kg
