Answer 11

My answer is $1.72. I divided 2.27 by 3.91. This is how I did it:

2.27/3.91 and 1/X  , I first multiplied the denominator(Bottom of fraction) of the first fraction by one which was the numerator(number at top of fraction) of the second fraction.Then I divided what I multiplied by the number on top of first fraction to get my answer. Hope this helps.
