Rewrite the fraction pairs with common denominators A. 3/20 and 4/5

B. 8/21 and 6/7

C. 2/8 and 4/9

a) and =

b) and =

c) and =

Step-by-step explanation:

a) and

x 4 =

and =

b) and

x 3 =

and =

c) and

x 9 =

x 8 =

and =

< 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

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
