Ingrid collected 6 cans of food and 18 boxes of food for the food bank. Which describes the relationship between cans of food and boxes of food?

The relationship between the cans of food and boxes of food that Ingrid collected can be determined by the mathematical equations involving addition/subtraction and multiplication/division.

For addition/subtraction:

D = x - y

Where D is difference, x is the number of cans of food, and y is the boxes. Substituting the known values,

D = 6 - 8 = - 2

For multiplication/division:

R = x/y

Where R is the ratio. Substituting the known values,

R = 6/8 = ¾ = 0.75
