Answer:

Step-by-step explanation:

According to the given question:

There are totally 8 parts made out of the alloy,

1) 5parts is copper ;

2) 2 parts is zinc....

Also given that:

1) 5 parts of alloy.....30.5g

then,2) 2 parts of alloy....?g.

Let the required weight be X.

# X= ( 30.5×2)÷5

# X= 12.2g..

So, the required weight of zinc is 12.2 grams..

Answer 2

Answer:

14.2

Step-by-step explanation:

5 parts = 35.5

1 part = 7.1

2 parts = 14.2
