Question

A:B=3:4 and B:C =7:2 then find A:C? *​

Answer 1

Answer:

21 : 8

Step-by-step explanation:

A:B=3:4

A/B = 3/4

A = 3/4 B..... (1)

B:C =7:2

B/C = 7/2

B = 7/2 C.... (2)

From equations (1) & (2)

$A = \frac{3}{4} \times \frac{7}{2} C \\ \\ A = \frac{21}{8} \\ \\ \frac{A}{C} = \frac{21}{8} \\ \\ A :C = 21 : 8$
