Mathematical Processes
When modeling sums such as $$\frac{4}{6}$$ and $$\frac{3}{6}$$, why is it helpful to combine parts into wholes when possible? Explain.
If we make a whole then adding the remaining fractions will be easy.

Example Subtract mixed numbers.

Alejandro had 3$$\frac{4}{6}$$ quesadillas. His family ate 2$$\frac{3}{6}$$ of the quesadillas. How many quesadillas are left?

Find 3$$\frac{4}{6}$$ – 2$$\frac{3}{6}$$

Model

Shade the model to show 3$$\frac{4}{6}$$.
Then cross out 2$$\frac{3}{6}$$ to model the subtraction. The difference is $$\frac{1}{6}$$.
So, there are __________ quesadillas left. The difference is _________ .
So, there are 1$$\frac{1}{6}$$.quesadillas left.
Explanation:
$$\frac{4}{6}$$. – $$\frac{3}{6}$$.
$$\frac{1}{6}$$.
Then subtract the wholes
3 – 2 = 1 Converted $$\frac{1}{6}$$. to 1$$\frac{1}{6}$$.

Record

Subtract the fractional parts of the mixed numbers.
Then subtract the whole-number parts of the mixed numbers.  Explanation:
Subtracted the fractions first
$$\frac{4}{6}$$. – $$\frac{3}{6}$$.
$$\frac{1}{6}$$.
Then subtract the wholes
3 – 2 = 1 Converted $$\frac{1}{6}$$. to 1$$\frac{1}{6}$$.

Mathematical Processes
Explain how adding and subtracting mixed numbers is different from adding and Subtracting fractions.
In fractions first we make denominators equal
then add or subtract the fractions directly
Explanation:
In mixed fractions first add or subtract the wholes

Problem Solving

Question 7.
The driving distance from Alex’s house to the museum is 6$$\frac{7}{10}$$ miles. What is the round-trip distance?
Answer: 13$$\frac{4}{10}$$ is the round trip distance
Explanation:
6$$\frac{7}{10}$$ + 6$$\frac{7}{10}$$
$$\frac{7}{10}$$ + $$\frac{7}{10}$$  = $$\frac{14}{10}$$
6 + 6 = 12
6 + 6 + 1 + $$\frac{4}{10}$$ = 13$$\frac{4}{10}$$

Question 8.
H.O.T. Apply Multi-Step The driving distance from the sports arena to Kristina’s house is 10$$\frac{9}{10}$$ miles. The distance from the sports arena to Luke’s house is 2$$\frac{7}{10}$$ miles. How much greater is the driving distance between the sports arena and Kristina’s house than between the sports arena and Luke’s house?
Answer: 8$$\frac{2}{10}$$
Explanation:
10$$\frac{9}{10}$$ – 2$$\frac{7}{10}$$ miles.
Subtract the wholes 10 – 2 = 8
then subtract the fractions $$\frac{9}{10}$$ – $$\frac{7}{10}$$
8$$\frac{2}{10}$$ is the driving distance between the sports arena and Kristina’s house than between the sports arena and Luke’s house

Question 9.
Benji biked from his house to the nature preserve, a distance of 23$$\frac{4}{5}$$ miles. Jade hiked from her house to the lake, a distance of 12$$\frac{2}{5}$$ miles. How many fewer miles did Jade bike than Benji?
Answer: 11$$\frac{2}{5}$$ fewer miles did Jade bike than Benji
Explanation:
23$$\frac{4}{5}$$ – 12$$\frac{2}{5}$$
Subtract the wholes 23 – 12 = 11
then subtract the fractions $$\frac{4}{5}$$  – $$\frac{2}{5}$$ = $$\frac{2}{5}$$
11$$\frac{2}{5}$$

Question 10.
H.O.T. Apply During the Samson family trip, they drove from home to a ski lodge, a distance of 55$$\frac{4}{5}$$ miles, and then drove an additional 12$$\frac{4}{5}$$ miles to visit friends. If the family drove the same route back home, what was the distance traveled during their trip?
Answer: 68$$\frac{3}{5}$$
55$$\frac{4}{5}$$ + 12$$\frac{4}{5}$$
add the wholes 55 + 12 = 67
$$\frac{4}{5}$$ + $$\frac{4}{5}$$ = $$\frac{8}{5}$$ = 1$$\frac{3}{5}$$
68$$\frac{3}{5}$$

(C) 1$$\frac{1}{6}$$
(D) 2$$\frac{1}{6}$$
Explanation:
2$$\frac{5}{6}$$ – 1$$\frac{4}{6}$$  = 1$$\frac{1}{6}$$ longer is the chameleon’s tongue than its body

Question 12.

(A) 1$$\frac{1}{12}$$
(B) 1$$\frac{11}{12}$$
(C) 9$$\frac{1}{12}$$
(D) 9$$\frac{11}{12}$$
Explanation:
5$$\frac{6}{12}$$ + 4$$\frac{5}{12}$$ = 9$$\frac{11}{12}$$ is the horse trail

Question 13.
Multi-Step Students bring 8$$\frac{7}{8}$$ gallons of lemonade to a picnic. They drink 5$$\frac{2}{8}$$ gallons with lunch. Then they drink 2$$\frac{1}{8}$$ gallons with an afternoon snack. How much lemonade is left?
(A) 3$$\frac{5}{8}$$ gallons
(B) 6$$\frac{3}{4}$$gallons
(C) 5$$\frac{3}{4}$$gallons
(D) 1$$\frac{1}{2}$$gallons
Explanation:
5$$\frac{2}{8}$$ + 2$$\frac{1}{8}$$ = 7$$\frac{3}{8}$$
8$$\frac{7}{8}$$ – 7$$\frac{3}{8}$$ = 1$$\frac{4}{8}$$
= 1$$\frac{1}{2}$$gallons lemonade is left
