nirections Solving Problems involving Proportion: Study the examples on how to determine indicated quantities from a given proportion, then solve the items labeled as Your Task. Examples If xy=5:4 , find 4x - 3y: 4x + y Solution: 5y 4*=5y use : 4 *x-3y Your Task 1.Find if 5p - 27:10 = 1:7 P 1 - 5 to find + $(5y) - 3y +y 4x - 3y 4x +y A(5y) 其 A Sy 3y Syy 27 67 1 3 Therefore, 4x-3y : 4x + y = 1:3 m If m and n represent two non-zero 2. Solve for the ratio d:e numbers find the ratio m: n if d2+ 3de - 10 e? = 0 if 2m2 - 5mn - 3n2 = 0 Solution: 2mº - 5mn - 3n2 = 0 (2m + n)(m - 3n) = 0 2m +2= m- 3n = 0 m=3n To find the ratio min 2m 3n 2n 2u 12 11 2 11 Hence, m: n = -1:2 or 3:1
