Alex walks 3 miles per hour. So if he need to find how much time he will need to get to school, you just have to divide the distance from school by his miles per hour. 2.25/3 which equals 0.75. 0.75 is the percent of an hour he needs to walk 2.25 miles. To find the total minutes, multiply 0.75 by 60 to get 45. Alex takes 45 minutes to walk to school.
Answer:
I think the answer is 8
Step-by-step explanation:
The unknown number . . . . . (z)
The sum of the unknown number and 22 . . . . . (z + 22)
The sum of the unknown number and 22
divided by the same unknown number . . . . . . . (z + 22) / z
You said that quotient is 12. (z + 22) / z = 12
Multiply each side by 'z' : (z + 22) = 12 z
Subtract 'z' from each side: 22 = 11 z
Divide each side by 11 : 2 = z .
Change 4 and 2/3 to an improper fraction.
4 + 2/3 = 14/3
There are 14 of the 1/3 lb serving in 4 and 2/3 pounds of cheese.
