Answer 2

The number of teaspoons of vanilla required for 5 cups of flour  = $2\dfrac{1}{2}$ .

Explanation:

Given : A cookie recipe states for every 3 cups of flour, $1\dfrac{1}{2}$  teaspoons of vanilla are needed.

$1\dfrac{1}{2}=\dfrac{3}{2}$

Let x be the number of teaspoons of vanilla required for 5 cups of flour.

if we follow recipe , then the number of cups of floor is directly proportional to the teaspoons of vanilla.

Then,

$\dfrac{x}{5}=\dfrac{\dfrac{3}{2}}{3}\\\\ \dfrac{x}{5}=\dfrac{3}{6}\\\\ x=\dfrac{3}{6}\times5=\dfrac{5}{2}=2\dfrac{1}{2}$

Hence, the number of teaspoons of vanilla required for 5 cups of flour  = $2\dfrac{1}{2}$ .
