Jeremy swims 5 3/5 kilometers in a 7- day periodHe swims the same distance each day. What distance does he swim in a day ? 39 1
denpristay [2]

Answer:

The distance Jeremey swims in a day is 4/5 Kilometers per day.

Solving:

(28/5)/7 = 28/7x5 = 4/5 kilometers per day

{when I put the / it means fraction}

explanation:

You have to turn 5 3/5 into an improper fraction, and do to do that you have to do 5 x 5 = 25 then 25 + 3 = 28/5

so in a 7 day period she swims 5.6 kilometers. So you have to do 5.6/7 = 0.8

So it would be 0.8 kilometers in a day which is 4/5 kilometers
