Question

The ratio of Copper and Zinc in an alloy is 9 ratio 8.8 if the big of zinc in the allow it 9 ratio 9.6 kilogram

Answer 1

Answer:

Step-by-step explanation:

Given

Ratio of copper and zinc in an alloy =9:8  

Weight of zinc in an alloy =9.6kg

Let xkg be the weight of copper in the alloy

Hence the weight of copper can be calculated as below  

9:8=x:9.6

⟹  

8

9

​  

=  

9.6

x

​  

 

⇒8×x=9×9.6  

⇒x=  

8

9×9.6

​  

 

⇒x=  

8

86.4

​  

 

⇒x=10.8

Therefore the weight of copper in the alloy is 10.8kg
