Question

the ratio of copper and zinc in an alloy is 3 :5 . Find the quantity of copper and zinc in 32g of alloy

Answer 1

Step-by-step explanation:

3:5 = 3x+5x=8x

32 /8 =4

4× 3 =12

4×5 =20

so copper is 12 g

and zinc is 20 g

Answer 2

Answer:

x=4

3×4=12g copper

5×4=20g zinc

12g of copper + 20g zinc = 32g total alloy

Step-by-step explanation:

when the numbers are in ratio we can find tgem by applying x to them,

So the no. will be 3x g and 5x g which altogether makes 32g.

So let's add them and find the value..

3x + 5x = 32

8x = 32

x = 32/8

x = 4

3x = 3 × 4 = 12

5x = 5 × 4 = 20

12 + 20 = 32

12g + 20g = 32g
