Answer 2

Answer:

A. 90

Step-by-step explanation:

In order to solve this, we first have to write an equation based on the question. In our case, the equation is...

$100g = 300cal$

(we know that in 100 grams of some food there are 300 calories)

Now we just have to find out how many calories are there in 30 grams of the same food. We do it in the following way...

$100g = 300cal\\100g/3\frac{1}{3} = 300cal/3\frac{1}{3}\\\\30g = 90cal$

Therefore, there are 90 calories in 30 grams of this food.
