Hope it helps .... mark as brainliest

Step-by-step explanation:

The ratio is 4:3

let X be the common multiple of this ratio

so the proportion of copper is 4x and proportion of zinc is 3x

now the weight of alloy is given i.e. 343g

so we get,

4x + 3x = 343

7x = 343

X= 343/7

X= 49

3x = 49*3 = 147

4x = 49*4 = 196

so the proportion of Copper is 196g

and proportion of Tin 147g
