Question

A tin contains 18-5/6 liters of oil . if 3/5 of it used , how much is left now?​

Answer 1

Answer:

18 5/6 litres of oil was there in the tank.

Now, we have already used 3/5 of it. ( Don't confuse 3/5 of it with 3/5 litres)

3/5 of 18 5/6

= 3/5 x 113/6

= 339/30 = 113/10

Now to calculate the left,

113/6 - 113/10

{(113 x 10) - (113 x 6)}/30

(1130 - 678)/30

= 452/30 litres are still left
