Definition of Ratio :

Measures two different quantities measured in the same units

**Definition of Rate :**

a comparison of two

a comparison of two

**different**

**quantities measured in different units**

**What is the difference between ratio and rate ?**

**The difference between them is that ratio measures 2 different quantities in different units while rate measures2 different quantities in the same units.**

**Questions for page 60 :**

**Question for page 61 :**

**Who is the faster cyclist ?**

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

None, they are the same speed.

How do you know?

When you divide the km to the hours on both Trevor and Jillian is equals 28 km / h .

Coin Question :

How many pennies would htere be in 7 jars ? if there were 5840 pennies in 7 jars , how much would there be in a jar ?

You need to find the unit rate by dividing the numbers 5840 which is how much pennies there would be in 7 jars so you need to divide by 7 and that would equal 834.285 ... but i rounded to the nearest tenths.

The answer is 834 pennies in a jar .

PART 2

10 ÷ 4 = 2.5

ground beef - 0.5 x 2.5 = 1.25

medium onion, diced - 1 x 2.5 = 2.5

stalk celery finely diced - 1 x 2.5 = 2.5medium onion, 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

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

10 ÷ 1 = 10

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

GOODLUCK TO ALL ON THE TEST TOMORROW .. MAKE SURE TO STUDY !! =)
