Question

the ratio of zinc and copper in an alloy is 9:5 if the weight of copper in the alloy is 48.6 g, find the weight of zinc in it

Answer 1

48.6/5= 9.72
9.27*9= 87.48
so the Weight of Zinc is 87.48

Answer 2

Answer:

87.48 grams

Step-by-step explanation:

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

To Find :If the weight of copper in the alloy is 48.6 g, find the weight of zinc in it.

Solution:

Let the weight of zinc be x

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

The weight of copper in the alloy is 48.6 g

So, A.T.Q

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

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

$87.48=x$

Hence  the weight of zinc in it is 87.48 grams
