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.

Answer: It is easy to add the numbers than fractions

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.

Answer:

The difference is _________ .

So, there are 1\(\frac{1}{6}\).quesadillas left.

Explanation:

Add 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\(\frac{1}{6}\).

**Record**

Subtract the fractional parts of the mixed numbers.

Then subtract the whole-number parts of the mixed numbers.

Answer:

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.

Answer:

In fractions first we make denominators equal

then add or subtract the fractions directly

Explanation:

In mixed fractions first add or subtract the wholes

then add or subtract the fractions

Question 7.

The driving distance from Alexâ€™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\(\frac{7}{10}\)

first add the fractions

\(\frac{7}{10}\) + \(\frac{7}{10}\)Â = \(\frac{14}{10}\)

Then add the wholes

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 Kristinaâ€™s house is 10\(\frac{9}{10}\) miles. The distance from the sports arena to Lukeâ€™s house is 2\(\frac{7}{10}\) miles. How much greater is the driving distance between the sports arena and Kristinaâ€™s house than between the sports arena and Lukeâ€™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 Kristinaâ€™s house than between the sports arena and Lukeâ€™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 \(\frac{4}{5}\)Â – \(\frac{2}{5}\) = \(\frac{2}{5}\)

11\(\frac{2}{5}\)

**Lesson 5.6 Answer Key Go Math Grade 4 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

Add the fractions

\(\frac{4}{5}\) + \(\frac{4}{5}\) = \(\frac{8}{5}\) = 1\(\frac{3}{5}\)

68\(\frac{3}{5}\)
