To find [tex]\( 7 \frac{1}{3} \div 2 \frac{1}{5} \)[/tex] and simplify the answer, follow these steps:

### Step 1: Convert the Mixed Numbers to Improper Fractions
First, convert the mixed numbers into improper fractions.
- For [tex]\( 7 \frac{1}{3} \: \[ 7 \frac{1}{3} = 7 + \frac{1}{3} = \frac{7 \times 3 + 1}{3} = \frac{22}{3} \] - For \( 2 \frac{1}{5} \: \[ 2 \frac{1}{5} = 2 + \frac{1}{5} = \frac{2 \times 5 + 1}{5} = \frac{11}{5} \] ### Step 2: Divide the Fractions To divide fractions, multiply by the reciprocal of the divisor. So, we calculate \(\frac{22}{3} \div \frac{11}{5}\)[/tex]:
[tex]\[ \frac{22}{3} \div \frac{11}{5} = \frac{22}{3} \times \frac{5}{11} \][/tex]

### Step 3: Perform the Multiplication
Multiply the numerators and the denominators:
[tex]\[ \frac{22 \times 5}{3 \times 11} = \frac{110}{33} \][/tex]

### Step 4: Simplify the Fraction
Simplify [tex]\(\frac{110}{33}\)[/tex] by finding the greatest common divisor (GCD) of 110 and 33, which is 11.
[tex]\[ \frac{110 \div 11}{33 \div 11} = \frac{10}{3} \][/tex]

### Step 5: Convert the Improper Fraction to a Mixed Number
Convert [tex]\(\frac{10}{3}\)[/tex] to a mixed number by dividing the numerator by the denominator.
[tex]\[ 10 \div 3 = 3 \text{ remainder } 1 \][/tex]
So, [tex]\(\frac{10}{3}\)[/tex] is [tex]\(3\frac{1}{3}\)[/tex].

Thus, the answer to [tex]\( 7 \frac{1}{3} \div 2 \frac{1}{5} \)[/tex] is [tex]\(\boxed{3 \frac{1}{3}}\)[/tex].
