Question

according to a salad recipe each serving requires 4 teaspoons of vegetable oil and 12 teaspoons of vinegar. if 14 teaspoons of vegetable oil were used how many teaspoons of vinegar should be used

Answer 1

Answer:

42 teaspoons of vinegar

Step-by-step explanation:

Given

$x \to vegertable$

$y \to vinegar$

$x : y = 4 :12$

Required

Find y when $x = 14$

$x : y = 4 :12$ implies that:

$14 : y = 4 : 12$

Express as fraction

$\frac{y}{14} = \frac{12}{4}$

$\frac{y}{14} = 3$

Multiply by 3

$y = 14* 3$

$y = 42$
