Answer:

1\frac{7}{15}

Step-by-step explanation:

Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog.

To find the total liters of water he drank, we should add up the liter of water  he drank on Monday before going jogging and  liter of water after his jog.

4/5 + 2/3

Find the Lowest Common Multiple for 5 and 3 , which is 15.

= [(4×3) + (2×5)] /15

= 12 + 10/ 15

= 22/15

As a mixed Fraction, the answer

= 1\frac{7}{15}
