Question

The ratio of copper and zinc in an alloy is 5:7. if the alloy contains 35.5 gram of copper, how many gram of zinc does it contain

pls answer full explanation ;)

Answer 1

Answer:

Ratio of Copper and zinc = 5:7

Let the total wt of alloy=x

Xx5/12=35.5

x = 426 / 5 = 85.28g

zinc = 85.28x7/12=49.7g

Answer 2

Answer:

Step-by-step explanation:

the ratio of copper and zinc =5:7

let the total weight of alloy be x

x  5 =35.5

  12

x = 426   =85.28 g

        5

zinc = 85.28 x   7

                         12
