Nicole is making tuna salad for her office colleagues. It takes 2/5 of a pound of canned tuna to make 5 portions of salad. She uses 1 1/5 pounds of canned tuna for every 2 onions used. If Nicole uses a total of 4 onions, then how many portions of salad does she make?

30 portions of salad

Step-by-step explanation:

Given that :

2/5 pounds of canned tuna = 5 portions of salad

For every 2 onions used, 1 1/5 pounds of canned tuna is used ;

Number of onions used = 4

If 4 onions were used, number of canned tuna used is ;

4 /2 * 1 1/5

= 2 * 1 1/5

= 2 * 6/5

= 12 / 5 = 2 2/5 pounds of canned tuna

Number of Portions of salad made :

2/5 pounds = 5 portions of salad

12/5 pounds = x

2/5 * x = 12/5 * 5

2/5x = 60 /5

2/5 x = 12

x = 12 ÷ 2/5

x = 12 * 5 /2

x = 60/2

x = 30 portions of salad
