To solve the problem of dividing 49\frac{4}{9} by 13\frac{1}{3}, we follow these steps:

  • Step 1: Convert the division operation into multiplication by the reciprocal of the second fraction.
  • Step 2: Perform the multiplication of the fractions.
  • Step 3: Simplify the resulting fraction, if possible, and convert it into a mixed number.

Let's proceed with the steps:

Step 1: The expression 49:13\frac{4}{9} : \frac{1}{3} is equivalent to multiplying 49\frac{4}{9} by the reciprocal of 13\frac{1}{3}. The reciprocal of 13\frac{1}{3} is 31\frac{3}{1}.

Step 2: Multiply the fractions:

49×31=4×39×1=129.\frac{4}{9} \times \frac{3}{1} = \frac{4 \times 3}{9 \times 1} = \frac{12}{9}.

Step 3: Simplify the result by dividing both the numerator and the denominator by their greatest common divisor (GCD), which is 3:

129=12÷39÷3=43.\frac{12}{9} = \frac{12 \div 3}{9 \div 3} = \frac{4}{3}.

Step 4: Convert the improper fraction 43\frac{4}{3} into a mixed number. 43\frac{4}{3} equals 11 with a remainder of 11, so it can be written as the mixed number 1131\frac{1}{3}.
