Answer:

3/4 hours or 45 minutes

Step-by-step explanation:

3 hours and 45 minutes is equivalent to 3 3/4 hours

We divide 3 3/4 by 5 (the number of weeks) to receive how much Jeremiah practices per week

We convert 3 3/4 to an improper fraction and receive 15/4

We now have 15/4 ÷ 5 =

Convert 5 into a fraction

5/1

15/4 ÷ 5/1 =

Keep, change, flip

We keep our first fraction

15/4 ÷ 5/1 =

Change our sign from division to multiplication

15/4 • 5/1 =

And flip or find the reciprocal of the second fraction

15/4 • 1/5 =

Then we multiply our numerators together and our denominators together

15/4 • 1/5 = 15/20

Then we simplify our fraction by dividing the numerator and denominator by the largest common factor, 5

15/5= 3

20/5= 4

And we receive our answer: 3/4 hours

Jeremiah practiced 3/4 hours or 45 minutes on the 5th week.
