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