Question

if A's one day's work is 3/20, then A can finish the whole work in _____ days​

Answer 1

If A's one days work is 3/20, then A can finish the whole work in 7 and half days

Answer 2

Answer:

6 whole 2/3

Step-by-step explanation:

think if some 1 asks you "if a can do a work in 15 days, how much can he do it in a day?

pretty simple indeed it's 1/15th part

so apply the same formula just the question is given in a tricky way

Hence the reciprocal will be 20/3 and since it's an improper fraction make it mixed =6 whole 2/3

hope you got it
