Question

if A:B =4:5 and B:C=6:7 and C:D=14:15 find ​

Answer 1

Answer:

A : D = 16 : 25

Step-by-step explanation:

Given that A:B = 4:5, B:C = 6:7 and C:D = 14:15.

Therefore, A/B =4/5; B/A = 6/7; C/D = 14/15

We can write A/D as A/D = A/B * B/C *C/D = 4/5 * 6/7 * 14/15 = 16/25

Thus, A : D = 16 : 25.
