<span>To find the greatest perfect square that is a factor of 396, first we check what are the factors of 396 Factors of 396 are: 1,2,3,4,6,9,11,12,18,22,33,36,44,66,99,132,198,396 Now we check which is the greatest perfect square in these. 396, 198, 132, 99, 66,44 are not perfect square, so 36 is the largest perfect square from the factors of 396, 6 x 6 = 6</span>² = 36
Answer: 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
