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
