Question

Suppose that a cows give b gallons of milk in c days. At this rate, how many gallons of milk will dd cows give in e days?

Answer 1

'A' cows ==> 'B' gallons ==> in 'C' days

'A' cows ==> (B)/(C) gallons per day

1 cow ==> (B)/(A·C) gallons per day


1 cow ==> (B·E)/(A·C) gallons in 'E' days

'D' cows ==> (B·D·E)/(A·C) gallons in 'E' days.
