Are 2/3 and 10/15 proportional?. Yes; 2/3 = (2*5)/(3*5) = 10/15. Are 2/3 and 4/9 proportional?. No; both are simplified. Proportional Shapes. Remember to Silence Your Cell . Phone and Put It In Your Bag!. Proportional Variance. Two quantities . vary proportionally. iff as their corresponding values increase or decrease, the ratios of the two quantities are always equivalent.. Ratios. A . ratio. is a comparison of . two. numbers.. Example: Tamara has 2 dogs and 8 fish. The ratio of dogs to fish can be written in three different ways. ..  .  . ***. Be careful with the . Magumba. Lecture 3 . Proportionality. Ratios. If the ratio of A:B is 1:3 then A = 1/3 of B. For instance if you were to divide 20 oranges between A and B in the ratio 1:3 it means you have a total of 1 + 3 or 4 equal parts and each part is equal to 20/4 or 5 oranges, A gets 1 * 5 oranges and B gets 3 * 5 oranges.

Without and with tied observations explanation. Parallel Lines and Transversal. Alternate interior angles are congruent if the lines are parallel. Corresponding angles are congruent if the lines are parallel. Given the picture list all corresponding angles, list all Alternate interior angles (assume lines are parallel). Directly Proportional. Directly proportional: as one amount increases, . another amount increases at the same rate. .. Hence, the straight line when we graph information. Directly Proportional.
