Question

the ratio of and zinc in a an alloy is9:5 if the waight of copper in the alloy is 48.6gram find the waight of zinc in the alloy

Answer 1

let the weight of zinc be x
9/5=48.6/x
x=48.6×5/9
x=27
the weight of zinc in alloy is 27 gram

Answer 2

Answer:

The weight of zinc in the alloy is 27 gram.

Step-by-step explanation:

The ratio of copper and zinc in an alloy is 9:5.

The weight of copper in the alloy is 48.6 gram.

Let the weight of zinc in the alloy be x.

$\frac{copper}{zinc}=\frac{48.6}{x}$

$\frac{9}{5}=\frac{48.6}{x}$

$9x=243$

$x=\frac{243}{9}=27$

Therefore the weight of zinc in the alloy is 27 gram.
