Answer 1

copper = 3 1/2 gm = 7/ 2 gm

tin = 2 3/4 gm = 11/ 4 gm

copper : tin = 7/2 : 11/4

L.C.M (2,4) = 4

copper : tin = 7×4/2 : 11×4/4

= 14 : 11

Answer: 14 : 11

Answer 2

Answer:

Step-by-step explanation:

Weight of copper : Weight of tin

Weight of copper

3 1/2 = 7/2 grams

Weight of tin

2 3/4 = 11/4 grams

7/2 : 11/4

=> (7/2)/(11/4)

=> (7×4)/(11×2)

=> (7×2)/11

=> 14/11

Ratio = 14:11
