Please give correct answer, it urgent

please ​

Answer 1

Answer:

If A : B = 2 : 3 and B : C = 4 : 5, then A : B : C is :

[A]2 : 3 : 5

[B]5 : 4 : 6

[C]6 : 4 : 5

[D]8 : 12 : 15

8 : 12 : 15

$latex A : B = 2 : 3$

$latex B : C = 4 : 5$

$latex \therefore A : B : C = 2\times 4 : 3\times 4 : 3\times 5&s=1$

$latex = 8 : 12 : 15$

Hence option [D] is correct answer.

Answer 2

Step-by-step explanation:

a/b=4/3

=>a=(4/3)*b

again

b/c=12/15

=>c=(15/12)*b

hence

a/c={(4/3)*b}/{(15/12)*b}

=(4/3)*(12/15)

=16/15

=>a:c=16:15
