Okay; let's say you have... whatever it is you've posted. What then is your question...? :oops:

Also: What does the variable "X" stand for? Where are the fractions? (Does "X" stand for a fractional value?) What were the instructions for this (these?) exercise(s)?

Please reply with clarification, using standard web-safe formatting and showing all of your work and reasoning so far. Thank you! :D

To multiply fractions, simply multiply both numerators over both denominators:

\(\displaystyle \L \frac{2}{3} \cdot \frac{3}{7}\,=\,\frac{6}{21} = \frac{2}{7}\)

Cheers-
John.

Are the two products added to one another? Are you supposed to multiply each pair and then convert each product to a common denominator to compare them? Or are you supposed to do something else with these? :?:

What, word for word, were the instructions for this exercise? What have you tried so far? Please be specific. Thank you! :D

Assuming these are two different problem and without using "special" formatting - you should write the problems as:

2/3 * 3/7 = (2*3)/(3*7) = 6/21 = 2/7

and

2/9 * 5/7 = (2*5)/(9*7) = 10/63
