Exercise – 9.3

Question 1.

Arya adds \(\frac{4}{7}\) litres of apple juice to \(\frac{2}{7}\) litres of organge juice to make a fruit punch. How many litres of fruit punch does he have now?

Solution:

Quantity of apple juice = \(\frac{4}{7}\) litres

Quantity of orange juice = \(\frac{2}{7}\) litres

Quantity of fruit punch = \(\frac{4}{7}\) + \(\frac{2}{7}\)

= \(\frac{4+2}{7}\)

= \(\frac{6}{7}\) litres

Solution:

Actual length of ribbon = \(\frac{5}{9}\)

Length of takenout piece = \(\frac{2}{9}\)

Length of remaining ribbon = \(\frac{5}{9}\) – \(\frac{2}{9}\)

= \(\frac{3}{9}\)

Question 3.

If kishore ate \(\frac{9}{10}\) of a pizza and Adi ate \(\frac{6}{10}\) of another pizza of same size, then how much more pizza did kishore eat than Adi?

Solution:

Kishore ate pizza size = \(\frac{9}{10}\)

Adi ate pizza size = \(\frac{6}{10}\)

Difference = \(\frac{9}{10}\) – \(\frac{6}{10}\) = \(\frac{9-6}{10}\) = \(\frac{3}{10}\)

Kishore ate \(\frac{3}{10}\) than Adi.

Question 4.

A scooter tank has \(\frac{2}{3}\) litres of petrol. Prasad rides around for some time and sees that the petrol level has come down to \(\frac{1}{3}\) litres. How much petrol does he use for riding around ?

Solution:

Quantity of petrol in the scooter at first = \(\frac{2}{3}\)

Quantity of petrol in the after ride = \(\frac{1}{3}\)

Quantity of petrol he used = \(\frac{2}{3}\) – \(\frac{1}{3}\)

= \(\frac{2-1}{3}\) = \(\frac{1}{3}\)

Question 5.

Krishna covered \(\frac{1}{5}\)th of his journey to school and suddenly he realizes that he had forgotten to bring his maths book. So, he walked back and returned to school in time. What is the extra distance he walked than usual ?

Solution:

Covered distance by Krishna at first = \(\frac{1}{5}\)

Again he covered distance = \(\frac{1}{5}\)

Total distance he covered = \(\frac{1}{5}\) + \(\frac{1}{5}\)

= \(\frac{2}{5}\)
