Question

if 2a equal to 3b and 4b equal to 5c then A : C =?

Answer 1

Answer:

a : c = 15 : 8

Step-by-step explanation:

2a = 3b   So 8a = 12b

4b = 5c    S0 12b = 15c

this means 8a = 15 c

or a/c = 15/8

a : c = 15 : 8

Answer 2

Answer:

Step-by-step explanation:

If 2a=3b

Then b=2a/3

Again 4b=5c

=>4(2a/3)=5c

=>8a/3=5c

=>8a/5c=3

=>a/c=3*5/8

=15/8

=15:8
