Find the ratio and reduce to their lowest terms 9 months and 2 years

2 years: 9 months

We know that, 1 year =12 months

2 years =2×12 months

=24 months

Given

2 years: 9  months

This can be written as

=  

9months

24months

=  

3months

8months

=8  months :3 months  

Hence, 8 months: 3 months is the simplest form of 2 years :9 months

Step-by-step explanation:

a) We know,

1 year = 12 months

Therefore

2 years= 2×12

= 24 months

So

9:24 = 3:8

Answer - 3:8

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
