Step-by-Step Solution

To solve the problem of dividing the mixed number 1351\frac{3}{5} by the fraction 12\frac{1}{2}, follow these steps:

  • Step 1: Convert the mixed number to an improper fraction.
  • Step 2: Take the reciprocal of the divisor fraction.
  • Step 3: Multiply the improper fraction by the reciprocal.
  • Step 4: Simplify the resulting fraction if necessary.

Now, let's execute each step:

Step 1: Convert 1351\frac{3}{5} to an improper fraction. To do this, multiply the whole number 1 by the denominator 5 and add the numerator 3:

1×5+3=5+3=81 \times 5 + 3 = 5 + 3 = 8

This gives us 85\frac{8}{5}.

Step 2: Take the reciprocal of 12\frac{1}{2}, which is 21\frac{2}{1}.

Step 3: Multiply 85\frac{8}{5} by 21\frac{2}{1}:

85×21=8×25×1=165\frac{8}{5} \times \frac{2}{1} = \frac{8 \times 2}{5 \times 1} = \frac{16}{5}

Step 4: Simplify 165\frac{16}{5} by converting it back to a mixed number:

Divide 16 by 5, which results in 3 with a remainder of 1, giving us 3153\frac{1}{5}.

Therefore, the result of 135÷121\frac{3}{5} \div \frac{1}{2} is 3153\frac{1}{5}.

Answer

315 3\frac{1}{5}
