What is a direct proportion ?
Direct proportion is a type of proportionality relationship. For direct proportion, as one value increases, so does the other value and conversely, as one value decreases, so does the other value. The symbol ∝ represents a proportional relationship.
By using direct proportion:
1/3 cups of grapes = 4 servings.
X cups of grapes = 30 servings.
Cross-multiplying, we have:
4X = 1/3 x 30
4X = 10
X = 10/4
X = 5/2 cups of serving.
