Step by Step Explanation
I used the same method with all 6 questions, I had to tweak it slightly for the last 3 as they were mixed fractions.
For the first 3 questions, I used the number you had to make and multiplied it by the denominator. Let's use the first questions as an example.
We need to make 7 by adding something to 27/4. I multiplied 7 by 4 in order to get 28.
This means your goal is to get to 28/4.
The difference between 28/4 and 27/4 is 1/4. Meaning you only have to add 1/4 in order to make 7.
For the last 3 questions I first sorted the fractions out. Let's use the first question again on the right side as an example.
I made 5[tex]\frac{7}{8}[/tex] a top heavy fraction by first multiplying 5 by 8, which makes 40. I then added 40 to 7 making 47. Now the fraction is 47/8.
Now that we have our top-heavy fraction we do the same as last time. We need to make 7. So we multiply 7 by 8 and that makes 56. The difference between 56 and 47 is 9. So we need 9/8 in order to get to 56/8. We need a mixed fraction so 9/8 becomes 1[tex]\frac{1}{8}[/tex].
I hope this helps, if this was confusing don't be afraid to ask questions.

The manager of a dress shop recorded the number of dresses sold during the week, the data is as follows:
17, 15, 16, 20, 15, 19
Find the mean deviation for this data.
Select one:
1.91
2.21
1.67
4.98
Answer: The answer is 1.67
Step-by-step explanation:
First, find the mean by adding all of the numbers and divide them by how many numbers there are, so 17+15+16+20+15+19=102 Then 102/6= 17. Then take the mean and subtract it by every number, and make sure it is the number’s absolute value.
17-17=0, 15-17=2, 16-17=1, 20-17=3, 15-17=2, 19-17=2. Then add all of those numbers and divide them by how many numbers there are. 0+2+1+3+2+2=10. 10/6=1.67
Answer:
1.67
Step-by-step explanation:
[tex]\frac{17 + 15 + 16 + 20 + 15 + 19}{6} = \frac{102}{6} = 17[/tex]
distance from 17
17, 0
15, 2
16, 1
20, 3
15, 2
19, 2
[tex]\frac{0 + 2 + 1 + 3 + 2 + 2 }{6} = \frac{10}{6} = 1.67[/tex]
The cost to rent a boat can be modeled by the equation C = 18h + 35 where C is the total cost in dollars and h is the number of hours in which the boat is rented.
What is the dependent variable?
A. h
B. C
C. 18
D. 35
Answer:
the answer is B, C is the total of cost (the dependent variable) because it depends on the independent variable, which is h. the dependent variable always is dependent on the independent value, like, you need the total of hours that you are renting the boat to know how much you need to pay, it can't be the other way around.
In the elementary school, middle school, and high school, there are 107 teachers altogether. If 27% of the teachers work at the elementary school, 35% work at the middle school, and 38% work at the high school, How many teachers work at the elementary school, how many teachers work at the middle school, and how many teachers work at the high school?
Elementary school:
27% = 207/100 x 27 = 55.89 = 56 teachers
Middle school:
35% = 207/100 x 35 = 72.45 = 72 teachers
High school:
38% = 207/100 x 38 = 78.66 = 79 teachers
