### %%%%%'s Rate Growing Post.

Ratio compares quatities measured in the same units.
Rate compares two amounts measured in different units.

The difference between ratio and rate is that ratio is the comparison between two numbers with the same unit. For example 3 oranges to two oranges. On the other hand, a rate is an indication of the measurements of different units per unit. For example, the statement 3 oranges/ person shows the relationship between the measurement of oranges per person.

question 16

Gina earns \$78.00 for working 6 hours. Asad makes \$192.50 for working 14 hours. Determine each person's unit rate of pay. Who has a greater hourly rate of pay?
Asad has a greater hourly rate of pay than Gina.

Part 2:

The recipe above for spaghetti serves four people.

1) What would the recipe look like if it had to serve 10 people?

I would multiply the measurement of ingredients by 2.5 because 10 is 2.5 more than 4.

For example: 1/2 lb groundbeef

1/2 multiplied by 2.5 is 1.25. Therefore the ingredient for 10 people will be 1.25 lb of groundbeef.

2) What would the recipe look like if you only had to serve 1 person?

We know that the recipe serves 4 people. So to serve one person, divide the quantities by four.

For example: 14 oz can of tomatoes chopped.

14 divided by 4 is 3.5. So the recipe for this ingredient will be 3.5 oz can of tomatoes chopped.

Sorry. I know it's so late!
