Jecelyn's Rate Growing Post

Well here is my blog:

Definitions:

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

Questions:

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.

2.Choose one of the questions page 60 and answer it.

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

A)Estimate which is the better buy. Show your thinking.

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

B)Explain whether your answer in part a) is a ratio or a rate.

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

4) coin question

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

PART 2!!!!



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

Now how about 1 person?

• 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
