### Allysa's %%%%%'s Rate Growing Post

PART 1:

In class we were told to make a part one of a two part post.

Define:
Ratio-Compares 2 things of the same quantity.
Rate- Compares 2 quantities measured in different units.

What is the difference between a ratio and rate?
The difference between a ratio and rate, is that it measures with 2 different quantities and ratios are measured with the same units.

4. Determine the unit rate in each situation.
a) An orca swims 110 km in 2 h.

b) A Canada goose flies 800 km in 12.5 h.

c) Cathy plants 45 daffodils in 30 minutes.

10. Trevor rode his mountain bike 84 km in 3 h. Jillian rode 75 km in 2.5 h. Who is the faster cyclist? How do you know?

They have the same speed. I know because I used a ratio table showing all my work and explaining it properly.
COIN QUESTION

If the jar equals \$100 and there is 1635 coins in the jar, what is the unit rate for every dollar?

PART 2:

This recipe serves 4 people.

1) What would the recipe look like if it had to serve 10 people? Show your calculations.
Since it serves 4 people, you just divide it by 4 to get 1. Then multiply it by 10 for it to serve 10 people.
e.g.

1 1/4 lb ground beef
2 1/2 medium onion diced
2 1/2 celery finely sliced
2 1/2 clove of garlic
35 oz can of tomatoes chopped
1 1/4 can of tomato paste
2 1/2 tsp parsley
3 3/4 tsp basil
2 1/2 tsp oregano
2 1/2 tsp sugar
1 1/4 tsp Worchestershire Sauce
1 1/4 tsp seasoning salt
2 1/2 bay leaf

2) What would the recipe look like if you had to only serve 1 person? Show your calculations.
Since it serves 4 people, you just divide each ingredient by 4 so you can get 1.
e.g.

1/8 lb ground beef
1/4 medium onion diced
1/4 celery finely sliced
1/4 clove of garlic
3.5 oz can of tomatoes chopped
1/8 can of tomato paste
1/4 tsp of parsley0
