Answer :

ANSWER

3 tablespoons

EXPLANATION

Serena makes 2 cups of popcorn using 1 tablespoon of kernels.

Let the number of tablespoons of kernels she used to make 6 cups of popcorn be x.

So, we have that:

2 cups of popcorn = 1 tbs of kernels

6 cups of popcorn = x tbs of kernels

We can cross-multiply to get:

[tex]\begin{gathered} 2\cdot\text{ x = 1 }\cdot\text{ 6} \\ \text{Divide through by 2:} \\ x\text{ = }\frac{1\cdot\text{ 6}}{2} \\ x\text{ = 3 tablespoons} \end{gathered}[/tex]

She will need 3 tablespoons of kernels to make 6 cups of popcorn.
