If A:B=3:4 and B:C=6:7,find (I)A:B:C. (ii) A:C

Question

I dont know how to solve it with steps and tell me why did you do those steps in a detailed manner please

Answer 1

Instead of looking at the problem with a : symbol, try to see them as real ratios...A/B=3/4 Write all of the rations out, then find the requested rations in order using the 'dividing by a fraction rule' (aka multiply by the inverse... A:B:C = (A/B)/C Good luck!
