Answer is 11 lessons and 2/5th of a lesson
<em>/Hello!</em>
<u><em>See below</em></u>
<em>We need to find x. X being the answer to 1/9 divided by 12.</em>
<em>1/9÷12=1/108. </em>
<em>Now that we know what "x" equals, we can divide the others.</em>
<em>1/9x12=1 and 3/9 ------simplifed is------1 and 1/3</em>
<em>Convert any mixed numbers to fractions</em>
<em>.</em>
<em>Then your initial equation becomes:</em>
<em>1/9×12/1</em>
<em>Applying the fractions formula for multiplication,</em>
<em>=1×12/9×1</em>
<em>=12/9</em>
<em>Simplifying 12/9, the answer is</em>
<em>=1 and 1/3</em>
This is not correct.
1/9×1/12
Applying the fractions formula for multiplication,
=1×1/9×1/2
=1/108
This is correct.
Therefore, your answer is B. 1/9 x 1/12
