A:B=7:5 AND B:C=9:14
So take out the LCM of the B=45
So make B into 45=》
A:B=(7×9):(5×9) AND B:C=(9×5):(14×5)
A:B=63:45 and B:C=45:70

So;A:C=63:70

Making it in simplest form the answer would be
A:C=9:10

Hope it helps:)

A:B = 7:5
A/B=7/5
A= 7B/5

B:C= 9:14
B/C =9/14
C =14B/9

A:C = A/C
=7B /5. / 14B/9
= 7B / 5 × 9/14B
=9/10
=9:10
