guajiro [1.7K]

Answer: OPTION D

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

- Convert from 48 inches to foot. You know that 12 inches=1 foot. Then you have:

$(48inches)(\frac{1foot}{12inches})=4feet$

- Therefore, keeping on mind that 48 inches is 4 feet, and you must find the ratio that correctly compares 2 feet to 48 inches, you can write:

$ratio=\frac{2feet}{4feet}$

- Reduce the fraction, then:

$ratio=\frac{1}{2}$

- You can rewrite it as following:

$ratio=1:2$

3. Four chicken nuggets have 180 calories. How many calories are in 9 chicken

Lemur [1.5K]

Hey there! :)

Answer:

405 calories.

Step-by-step explanation:

To solve, we can create a proportion.

We are given that 4 nuggets is equivalent to 180 calories, therefore:

$\frac{180cal}{4}= \frac{xcal}{9}$

Cross multiply:

9 · 180 = 4 · x

1620 = 4x

Divide both sides by 4:

x = 405 calories.
