Question

in a recipe for pizza sauce, the ratio of cans of tomatoes to teaspoons of oregano is 1:4. how many teaspoons of oregano do you need for six cans of tomatoes?

Explanation:

Step1: Set up proportion.

Let $x$ be the number of teaspoons of oregano. The ratio is $1:4=\frac{1}{4}$, and we have the proportion $\frac{1}{4}=\frac{x}{6}$.

Step2: Cross - multiply.

$4x = 6\times1$.

Step3: Solve for $x$.

$x=\frac{6}{4}=\frac{3}{2}= 1.5$.

Answer:

$1.5$
