Solution

1) picnic salad has 15 beans

let black eyed beans = x

red beans are 3 times as black beans = 3x

lima bean = 3x+1

so we can write the equation as

x + 3x + 3x + 1 = 15

7x + 1 = 15

7x = 14

x = 2

hence , lima bean = 3x + 1 = 3(2) + 1 = 7

ratio of lima bean to whole salad = 7/15 = 7 : 15
