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. Add the number of yards of the two pieces.
[tex]2 \frac{1}{3} + 3 \frac{1}{3} = \text{ ? yards}[/tex]

2. Subtract what she has now from the total she needs.
[tex]10 - \text{(what she has)} = \text{? yards}[/tex]

Answer the question below:

What is the answer to this problem?
[tex]2 \frac{1}{3} + 3 \frac{1}{3} = ?[/tex]



Answer :

Let's solve the problem step-by-step.

First, we need to add the lengths of the two pieces of carpet runner that Arliss has:

1. Convert the mixed numbers to improper fractions:

- The first piece is [tex]\(2 \frac{1}{3}\)[/tex] yards. To convert this to an improper fraction:
[tex]\[ 2 \frac{1}{3} = 2 + \frac{1}{3} = \frac{6}{3} + \frac{1}{3} = \frac{7}{3} \][/tex]
- The second piece is [tex]\(3 \frac{1}{3}\)[/tex] yards. To convert this to an improper fraction:
[tex]\[ 3 \frac{1}{3} = 3 + \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3} \][/tex]

2. Add the improper fractions:
[tex]\[ \frac{7}{3} + \frac{10}{3} = \frac{7 + 10}{3} = \frac{17}{3} \][/tex]

3. Convert the improper fraction back to a mixed number:
[tex]\[ \frac{17}{3} = 5 \frac{2}{3} \text{ yards} \][/tex]

Therefore, the total length of the two pieces of carpet that Arliss has is:
[tex]\[ 2 \frac{1}{3} + 3 \frac{1}{3} = 5 \frac{2}{3} \text{ yards} \][/tex]

Now, we need to determine how much more carpet Arliss needs to buy. We know that she needs a total of 10 yards of carpet runner:

4. Subtract the total length she currently has from the total length she needs:
[tex]\[ 10 - 5 \frac{2}{3} \][/tex]

First, convert [tex]\(10\)[/tex] to a fraction with the same denominator:
[tex]\[ 10 = \frac{30}{3} \][/tex]

Next, subtract [tex]\(5 \frac{2}{3}\)[/tex]:
[tex]\[ \frac{30}{3} - \frac{17}{3} = \frac{30 - 17}{3} = \frac{13}{3} \][/tex]

Convert [tex]\(\frac{13}{3}\)[/tex] back to a mixed number:
[tex]\[ \frac{13}{3} = 4 \frac{1}{3} \text{ yards} \][/tex]

Therefore, Arliss needs to buy:
[tex]\[ 4 \frac{1}{3} \text{ yards} \][/tex]

So, the answer to the problem is:

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