Question

the ratio of copper and zinc is an alloy is 9:5 if the weight of copper is the alloy​

Answer 1

Answer:

Step-by-step explanation:

Given, copper : zinc = 9 : 5

Let, x be the common multiple.

Then, weight of copper = 9x grams

and weight of zinc = 5x grams

By the given condition,

9x = 48.6

⇒ x = 48.6 ÷ 9

⇒ x = 5.4
