At the title card, I'm going with c) (xw + yz)/(yw).

[@phongjasonnguyen3859]

C. Cross multiplication.

[@missirina6912]

We multiply both the denominator and the numerator by the same number (e.g. 5), because we cannot change the fraction, such we practically multiply those fractions by 1 (one), the neutral number of the multiplication 😃, which can be written either by 5/5 = 1, or 2/2 = 1, or w/w = 1, or y/y = 1.😄 We just peak the fraction which suits us, for 1/2 it will be 5/5, and for 3/5 it will be 2/2, for this way will get the same denominator, 10 (ten), and for x/y it will be w/w =1, and for z/w it will be y/y =1, in view to get the same denominator, y•w !

Thanks John! I looked at this, I choked, and I twisted up my brain… then, when I used the bowtie method… I untwisted up my brain and got the right answer!

oh! how easy!..... lyrics: ...... C.

[@raynewport9395]

You imply that being unable to answer a question that is irrelevant to most people is somehow a fault in them. Possibly this is unfair.

[@heidicameron2015]

B.

[@artcraftmathcareenjoylearn1434]

C is the correct answer
