Answer (1)
Exercise 2; Directions: Find the value of y using the type of proportion indicated.11. y:8 = 16:4 (direct proportion)y = (8 x 16) / 4y = 3212. 24:y = 12:22 (inverse proportion)y = (24 x 22) / 12y = 4413. 20:14 = y:20 (inverse proportion)y = (20 x 14) / 20y = 1414. 30:16 = 10:y (inverse proportion)y = (30 x 10) / 16y = 18.7515. 90:24 = y:72y = (90 x 72) / 24y = 27016. 42:y = 30:90 (direct proportion)y = (42 x 90) / 30y = 12617. 36:10 = y:60y = (36 x 60) / 10y = 21618. 4y:24 = 30:4 (direct proportion)y = (24 x 30) / (4 x 4)y = 4519. 6:6y = 50:90 (direct proportion)y = (6 x 90) / 50y = 10.820. 24:10y = 54:130 (inverse proportion)y = (24 x 130) / (10 x 54)y = 57.41Note:- Direct proportion: y = (a x b) / c- Inverse proportion: y = (a x c) / b#CarryonlearningHope this helped your studies!!
