### tamika's rate growing post, nov.1

Ratio- is when you compare different amounts of a unit to other amounts of that same unit.

Rate- is when you compare two amounts in different units.

A rate is different from a ratio because it compares the amounts in different units instead of one unit.

page 60 question 9

Mala is shopping for honey. Her favourite brand is available in two sizes.

answer) I think the big one might be the better buy. If you guesstimate what the money amount would be on the small one if you multiplied it a few times it becomes more than the amount of money of the big one.

answer) The big one is the better buy. Here is my evidence:

question 11 page 61
Shannon buys 12 granola bars for \$9.96
A) Determine the price per bar. Give your answer in dollars and cents.

a) It is a rate because you are looking at two different units.

Now i'm making a question about the coin ratio math, but it is a rate question.

How many coins would it take to make \$50 in Canadian and American coins?
Canada: you would have 755 coins if there was 10 loonies, 5 toonies, 40 quarters, 100 dimes, 100 nickles, and 500 pennies.
America: you would have 880 coins if there was 80 quarters, 200 dimes, 100 nickles, and 500 pennies.

Q1) what would the recipe be if it served 10 people? show your calculations.
4servings x 2.5=10servings
1/2lb=0.5
0.5 x 2.5=1.25lb ground beef
1 x 2.5= 2.5 medium onion diced
1 x 2.5= 2.5 celery finely sliced
1 x 2.5= 2.5 clove garlic
14 x 2.5= 35 oz can tomatoes chopped
0.5 x 2.5= 1.25 can of tomato paste
1 x 2.5= 2.5 tsp parsley
1.5 x 2.5= 3.75 tsp basil
1 x 2.5= 2.5 tsp oregano
1 x 2.5= 2.5 tsp sugar
0.5 x 2.5= 1.25 tsp worchestershire sauce
0.5 x 2.5= 1.25 tsp seasoning salt
1 x 2.5= 2.5 bay leaves

Q2) what would the recipe be if it was for 1 person? show your calculations.
10servings divided by 10 equals 1serving
1.25 ÷ 10= 0.125 lb ground beef
2.5 ÷ 10= 0.25 medium onion diced
2.5 ÷ 10= 0.25 celery finely sliced
2.5 ÷ 10= 0.25 clove garlic
35 ÷ 10= 3.5 oz can tomatoes chopped
1.25 ÷ 10= 0.125 can of tomato paste
2.5 ÷ 10= 0.25 tsp parsley
3.75 ÷ 10= 0.375 tsp basil
2.5 ÷ 10= 0.25 tsp oregano
2.5 ÷ 10= 0.25 tsp sugar
1.25 ÷ 10= 0.125 tsp worchestershire sauce
1.25 ÷ 10= 0.125 tsp seasoning salt
2.5 ÷ 10= 0.25 bay leaf
