Question

If 3A = 4B and 4B = 5C then A:C?​

Answer 1

Step-by-step explanation:

A=4B/3

=C=4B/5

Then,

=A:C=(4B/2):(4B/5)

=(A/C)=(4B/2)/(4B/5)

=(A/C)=(4B/2)×(5/4B)

=(A/C)=(20/8)

=A:C=20:8

Answer 2

Answer:

3/2:4/5

Step-by-step explanation:

3A=4B

A=4B/3

4B=5C

C= 4B/5

A:C = 4B/3 : 4B/5

therefore, 4B/3 divided by 4B/5

4B/3 × 5B/4

A:C = 20 : 12
