An alloy contains 120g of copper and 150g of zinc. Find the
a. Ratio of copper and zinc.
b. Ratio of copper and total weight of the alloy.
c. Zinc and total weight

Answer 1

Answer:

Step-by-step explanation:

Given the ratio of copper and zinc in an alloy is 5:3.

Let weight of copper and zinc be 5x and 3x.

Then according to the problem we have,

5x=30.5

or, x=6.1

Then weight of zinc is 3×6.1=18.3 g.
