Arliss has two pieces of carpet runner. One is [tex]$2 \frac{1}{3}$[/tex] yards long and the other is [tex]$3 \frac{1}{3}$[/tex] yards long. She needs 10 yards of carpet runner altogether. How much more does she need to buy?

1. Write and solve the arithmetic problem for each step.
- Add the number of yards of the two pieces:
[tex]\[
2 \frac{1}{3} + 3 \frac{1}{3} = 5 \frac{2}{3} \text{ yards}
\][/tex]
- Subtract what she has now from the total she needs:
[tex]\[
10 - 5 \frac{2}{3} = \text{? yards}
\][/tex]

2. Answer the question below. Type your response in the space provided.
[tex]\[
10 - 5 \frac{2}{3} = \text{?}
\][/tex]

Done
Clear



Answer :

To determine how much more carpet runner Arliss needs to buy, let's solve this step-by-step:

1. Add the length of the two pieces of carpet runner she currently has:
Arliss has two pieces of carpet runner: one is [tex]\(2 \frac{1}{3}\)[/tex] yards long and the other is [tex]\(3 \frac{1}{3}\)[/tex] yards long.

First, convert these mixed numbers into improper fractions:
[tex]\[ 2 \frac{1}{3} = \frac{6}{3} + \frac{1}{3} = \frac{7}{3} \][/tex]
[tex]\[ 3 \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3} \][/tex]

Now, add the two improper fractions:
[tex]\[ \frac{7}{3} + \frac{10}{3} = \frac{17}{3} \][/tex]

Convert the result back into a mixed number:
[tex]\[ \frac{17}{3} = 5 \frac{2}{3} \text{ (since } 17 \div 3 = 5 \text{ remainder } 2) \][/tex]

Therefore, the total length of the carpet runner she currently has is [tex]\(5 \frac{2}{3}\)[/tex] yards.

2. Determine how much more carpet runner she needs to buy:
She needs 10 yards of carpet runner in total. We need to find the difference between the total needed and what she currently has.

Subtract the mixed number [tex]\(5 \frac{2}{3}\)[/tex] from 10:
[tex]\[ 10 - 5 \frac{2}{3} \][/tex]

First, convert [tex]\(5 \frac{2}{3}\)[/tex] into an improper fraction:
[tex]\[ 5 \frac{2}{3} = \frac{15}{3} + \frac{2}{3} = \frac{17}{3} \][/tex]

Now, rewrite 10 as a fraction with the same denominator:
[tex]\[ 10 = \frac{30}{3} \][/tex]

Perform the subtraction:
[tex]\[ \frac{30}{3} - \frac{17}{3} = \frac{30 - 17}{3} = \frac{13}{3} \][/tex]

Convert [tex]\(\frac{13}{3}\)[/tex] back into a mixed number:
[tex]\[ \frac{13}{3} = 4 \frac{1}{3} \text{ (since } 13 \div 3 = 4 \text{ remainder } 1) \][/tex]

Therefore, Arliss needs to buy an additional [tex]\(4 \frac{1}{3}\)[/tex] yards of carpet runner.

In conclusion:
[tex]\[ 10 - 5 \frac{2}{3} = 4 \frac{1}{3} \text{ yards} \][/tex]
So, Arliss needs to buy [tex]\(4 \frac{1}{3}\)[/tex] yards of carpet runner.
