Question

4. IF
A:B = 5:8 and B: C = 18:25, then find A:B:C.
​

Answer 1

                         Given,

A/B=5/8,. B/C=18/25

A/B=5/8 ×18 = 90/144 ( We get 90/144 by dividing both numerator and denominator by 18)

B/C=18/25 × 8= 144/200 ( By dividing both numerator and denominator by 8)

Now,

A/B/C = 90/144/200

= 45/72/100
