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
= 
Okay so you're trying to find the unit rate of 720yds/4min. If you divide 720 by 4 you will have the unit rate as 180yds/1 min or 60 sec then if you divide 180 and 60 by 4 again you will get the answer of 45yds/15sec.
5m/8 = 12
8 x 12 = 5m
96 = 5m
m = 96/5
= 19.2
