To find out how much butter she needs if she uses 10 tablespoons of kernels, we can set up a proportion based on the original recipe ratio.

The original recipe calls for:

  • 1/2 cup of butter for 3 tablespoons of kernels.

If she uses 10 tablespoons of kernels, we can set up the ratio as follows:

\[ \frac{1/2 \text{ cup butter}}{3 \text{ tablespoons kernels}} = \frac{x \text{ cups butter}}{10 \text{ tablespoons kernels}} \]

To find \(x\), we can cross-multiply:

\[ 1/2 \cdot 10 = 3 \cdot x \ 5 = 3x \]

Now, divide both sides by 3 to solve for \(x\):

\[ x = \frac{5}{3} \text{ cups butter} \]

So, she needs \(\frac{5}{3}\) cups of butter, which is approximately 1 cup and 2 tablespoons of butter.

round to the nearest hundereth

To round \(\frac{5}{3}\) cups of butter to the nearest hundredth, we first convert \(\frac{5}{3}\) to a decimal:

\[ \frac{5}{3} \approx 1.66666667 \]

Rounding this to the nearest hundredth gives:

\[ 1.67 \]

So, if she uses 10 tablespoons of kernels, she needs 1.67 cups of butter rounded to the nearest hundredth.
