Answer:

Below.

Step-by-step explanation:

The problem would look like this:

12 3/8 / 5 1/2

My math teacher told us to write it like a normal division problem.

12 3/8 ÷ 5 1/2

One way to solve is to turn both fractions into improper fractions, so..

12 3/8

So multiply 8 x 12 = 96 + 3 = 99/8

Then, 5 1/2, 2 x 5 = 10 + 1 = 11/2

99/8 ÷ 11/2, 99 ÷ 11 = 9, 8 ÷ 2 = 4,

So your answer would be 9/4, which is an improper fraction. To simply, just divide 9 by 4, and you would get 2 1/4 (mixed number).

Answer:9/4

Step-by-step explanation:

99/8*2/11=9/4*1/1=9/4

You can cancel out 99 and 11 to 9 and 1 as they are multiples of eac hother and you can do the same for 8 and 2 to 4 and 1

Morgarella [4.7K]

Answer: 24

Step-by-step explanation:

Colleen painted 7 windows, some of which were her mother's.

Her dad painted 7+1 (8) windows, and that is twice as much as what her mother was supposed to do. Her mother was supposed to do 4 windows. That means Colleen's share was 3 windows.

If all the kids had to do an equal amount of windows, than each kid had to do 3 windows.

8+7+3+3+3=24

The average (arithmetic mean) of k scores

denis23 [38]

Answer:

(E) (20k - 150)/(k - 10)

Step-by-step explanation:

Sum of all scores = average × number of scores = 20 × k = 20k

Sum of 10 scores = 15 × 10 =150

Sum of remaining scores = 20k - 150

Number of remaining scores = k -10

Average of remaining scores = sum of remaining/no. remaining

= (20 k -150)/(k-10)
