I don't understand proportional relationship can u help?

I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D

Two angles are Supplementary when they add up to exactly 180 degrees. They don't necessarily have to be next to each other, as long as the total adds up to be 180 degrees. (Hope this helps!) ^-^
