Answer:

(i) 3:10

(ii) 6:15:20

Step-by-step explanation:

a : b

2 : 5

b : c

3 : 4

Since both values of b in the two ratios are different, we need to multiply each ratio so that they are the same. I will multiply the first ratio by 3 and the second ratio by 5 so that b = 15 units.

a : b

6 : 15

b : c

15 : 20

Now that both values of b are the same, we can arrange the variables a, b and c together.

Thus:

a : b : c

6 : 15 : 20

a : c

6 : 20

3 : 10
