Final answer:
To solve the proportion 3/4 = v/14, cross multiply and divide to find that v = 42 / 4, which simplifies to v = 10.5.
Step-by-step explanation:
To solve the proportion 3/4 = v/14, we can use cross multiplication. This means we multiply the numerator of one fraction by the denominator of the other fraction, and set it equal to the product of the other numerator and denominator.
Here, that would be 3 times 14 equals 4 times v.
Multiplying these together, we get 3 × 14 = 4 × v, or 42 = 4 × v. To find v, we then divide both sides of the equation by 4, which gives us v = 42 / 4.
So, v equals 10.5. This means that the missing value in the proportion is 10.5.
