Question

if a:b=3:4,b:c=5:6,c:d=11:9 then what is a:d
solve this guys ????​

Answer 1

We know that a:b = 3:4 which implies 4a = 3b similarly 6b = 5c and 9c =11d

:   4a = 3b

:   8a = 6b (multiplying by 2)

:   8a = 5c (6b = 5c)

:   72a = 45c (multiplying by 9)

:   72a = 55d (9c = 11d)

Therefore a:d = 55:72

Hope this helps (✿◠‿◠)
