<h2>11.</h2>
Remember that <u>dividing by a number is the same as multiplying by its reciprocal.</u> To get a number's reciprocal, flip the numerator and denominator around.
In this case, 3/5's reciprocal is 5/3. With this information in mind, flip 3/5 to it's reciprocal, change the division sign to multiplication, then multiply as such:
<u>Your final answer is 35/24.</u>
<h2>12.</h2>Now firstly, we want to convert these mixed fractions into improper fractions. To convert them, multiply the whole number by the denominator then add the numerator and that's your new numerator. In this case:
Next, we want to convert this expression to multiplication. Similar to before, convert 6/5 to its reciprocal, change the multiplication sign to division, and multiply as such:
Now you may think that 105/60 is the right answer, however we can simplify it further. The numerator and the denominator have a GCF, or greatest common factor, of 15. With this, divide the fraction by 15/15 as such:
<u>Your final answer is 7/4.</u>
