Anita is eating popcorn at the movies. She eats 24 kernels in 10 minutes and 72 kernels in 30 minutes. Which TWO other ratios ca

Neporo4naja [7]

Answer:

$\dfrac{96}{40}$ and $\dfrac{120}{50}$

Step-by-step explanation:

24 kernels in 10 minutes

In 1 minute she can eat $\dfrac{24}{10}=\dfrac{12}{5}\ \text{kernels}$

let $x$ be the number of popcorn and minutes so the rate of eating popcorn is of the form

$\dfrac{x12}{x5}$

So, when $x = 6$ we get

$\dfrac{6\times12}{6\times 5}=\dfrac{72\ \text{kernels}}{30\ \text{minutes}}$

$x$ can be any real number

$\dfrac{10\times 12}{10\times 5}=\dfrac{120\ \text{kernels}}{50\ \text{minutes}}$

$\dfrac{8\times 12}{8\times 5}=\dfrac{96\ \text{kernels}}{40\ \text{minutes}}$

Other two ratios can be $\dfrac{96}{40}$ and $\dfrac{120}{50}$ .
