A serving of vanilla ice cream is 120 g. One serving contains 230 calories. If you have only 100 g of vanilla ice cream, how many calories did you have?

191  calories

Explanation:

Create a proportion where x is the number of calories

=

Cross multiply and solve for x

120x = 23000

x = 191

So, in 100g of ice cream, you will have 191 calories

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
