Question

An alloy is made with 3 gram of silver 18 gram of copper 6 gram of aluminium and three Gram of zinc find what part of the total is used for each metal?

​

Answer 1

see explanation

Explanation:

total parts = 3 + 18 + 6 + 3 = 30

3 grams of silver =
`(3)/(30)` =
`(1)/(10)`

18 grams of copper =
`(18)/(30)` =
`(3)/(5)`

6 grams of aluminium =
`(6)/(30)` =
`(1)/(5)`

3 grams of zinc =
`(3)/(30)` =
`(1)/(10)`
