Yes these rates to form a proportion. This is because if I am able to do 90 sit-ups in 2 minutes then the unit rate (amount of sit ups per minute) is 45. Since my friend does 135 sit-ups in 3 minutes then the unit rate is also 45. Both me and my friend do 45 sit-ups per minute.
He can conclude that the system of equations has no solution since one equation in it always results with false equivalency.
Hope this helps.

Her ratio of Wii Games to PS3 Games is 8:4. However, this can be simplified to the ratio 4:2, or fully simplified to the ratio 2:1.
