Help me pls in this question

a)3:8

b) 3:10

Step-by-step explanation:

To convert it into ratio and reduce into lowest terms we should bring both the terms into equivalent terms.

a) We know,

1 year = 12 months

Therefore

2 years= 2×12

= 24 months

So

9:24 = 3:8

b) We know

1 litre = 1000 ml

So 3 litre = 3×1000

=3000 ml

So,

900:3000

=9:30

=3:10
