Step-by-Step Solution

Since we are dividing two positive numbers, the result must be a positive number:

+:+=+ +:+=+

First, we'll convert each mixed fraction into an improper fraction as follows:

3313=3×13+313=39+313=4213 3\frac{3}{13}=\frac{3\times13+3}{13}=\frac{39+3}{13}=\frac{42}{13}

11213=1×13+1213=13+1213=2513 1\frac{12}{13}=\frac{1\times13+12}{13}=\frac{13+12}{13}=\frac{25}{13}

Now we have:

4213:2513 \frac{42}{13}:\frac{25}{13}

We'll convert the division problem into multiplication, remembering to switch the numerator and denominator:

4213×1325= \frac{42}{13}\times\frac{13}{25}=

We'll simplify the 13 to get:

4225= \frac{42}{25}=

Now we'll factor 42 into an addition problem:

25+1725=2525+1725= \frac{25+17}{25}=\frac{25}{25}+\frac{17}{25}=

Finally, we will solve accordingly to get:

1+1725=11725 1+\frac{17}{25}=1\frac{17}{25}

Answer

11725 1\frac{17}{25}
