Definitions:

- Define ratio: The relation between quantities (or parts of things)
- Define rate:Compares two quantities measured in different units

1.What is the difference between ratio and rate?

- A ratio is the comparison between two numbers with the same unit and a rate is the is an indication of the measurements of different units per unit.

- Mala is shopping for honey. Her favorite brand is available in two sizes
- Jar 1- 250 mL
- Jar 2-1000 mL

I think jar 1 is the better buy

Here is my thinking:

Jar 1 = 250 ml = $2.29

- 250/250=1
- 2.79/250=0.011=0.011 times 10 =$ 0.11/ml

Jar 2= 1000 ml

- 1000/1000=1
- 9.59/1000=0.0095=0.0095 times 100= $0.95/ml

3.Choose one of the questions on page 61 and answer it.

Shannon buys 12 granola bars for $9.96.

a) Determine the price per bar. Give your answer in dollars and cents.

- 12/12=1
- 9.96/12=0.83
- 0.83 for 1

- It is a rate because it express to quantities in different units.

- How long will it take for the jar to be filled in 1 year if you put 1 coin in the jar a day?

A)What would the recipe look like if it had to serve 10 people? Show your calculations.

- ground beef - 0.5 x 2.5 = 1.25 lb
- medium onion, diced - 1 x 2.5 = 2.5
- stalk celery finely diced - 1 x 2.5 = 2.5
- clove garlic, minced - 1 x 2.5 = 2.5
- canned tomatoes, chopped - 14 x 2.5 = 35 oz
- can tomato paste - 0.5 x 2.5 = 1.25
- parsley - 1 x 2.5 = 2.5 tsp
- basil - 1.5 x 2.5 = 3.75 tsp
- oregano - 1 x 2.5 = 2.5 tsp
- sugar - 1 x 2.5 = 2.5 tsp
- Worcestershire Sauce - 0.5 x 2.5 = 1.25 tsp
- seasoning salt - 0.5 x 2.5 = 1.25 tsp
- bay leaf - 1 x 2.5 = 2.5

- ground beef - 1.25 ÷ 10 = 0.125 lb
- medium onion, diced - 2.5 ÷ 10 = 0.25
- stalk celery finely diced - 2.5 ÷ 10 = 0.25
- clove garlic, minced - 2.5 ÷ 10 = 0.25
- canned tomatoes, chopped - 35 ÷ 10 = 3.5 oz
- can tomato paste - 1.25 ÷ 10 = 0.125
- parsley - 2.5 ÷ 10 = 0.25 tsp
- basil - 3.75 ÷ 10 = 0.375 tsp
- oregano - 2.5 ÷ 10 = 0.25 tsp
- sugar - 2.5 ÷ 10 = 0.25 tsp
- Worcestershire Sauce - 1.25 ÷ 10 = 0.125 tsp
- seasoning salt - 1.25 ÷ 10 = 0.125 tsp
- bay leaf - 2.5 ÷ 10 = 0.25
