    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.
