## Answers ( No )

1. Answer:168g

Step-by-step explanation:

The ratio of zinc to copper is 4 : 13

Copper = 546g ( from the question)

let zinc = x

so therefore

Zinc : copper

4 : 13

X : 546g

Then cross multiply

13X = 4 × 546g

13x = 2184g

X= 2184g/13

x= 168g

2. Given –

In a certain chemical, the ratio of zinc to copper is 4 to 13.

The chemical contains 546 grams of copper.

Prove  –

How many grams of zinc does it chemical contain.

Answer

suppose that scalar multiple of the  zinc and copper be y .

As given

In a certain chemical, the ratio of zinc to copper is 4 to 13.

The chemical contains 546 grams of copper.

Than equation is

13y = 546

13y = 546

y = 42

Zinc contain in the certain chemical = 4y

= 4 42

= 168 grams

Therefore 168 grams of zinc contain in a certain chemical .
