**questions :**

**How many pennies would there be in 7 jars ? if there were 5840 pennies in 7 jars , how much would there be in a jar ? 5840 divided by 7 = 834 . so there would be 834.. pennies in 7 jars.**

**Determine the unit rate in each situation.**

**question : An orca swims 110 km in 2 hours.**

You can get the answer by first getting the hours to 1 hour for the unit rate. so divid it by itself which is 2, then you get 1. You do the same to the other side and you get 55.

answer: orca whale swims 55 km/h

**question : A Canada goose flies 800 km in 12.5 hours.**

You divide each side by 12.5 and you get 64 on the km and 1 in the hours.

answer : Canada goose flies 64 km / h.

**question : Cathy plants 45 daffodils in 30 min.**

You multiply each side by 2. Which gets you the answer 90 daffodils/ h.

**part 2**

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

10 ÷ 4 = 2.5

ground beef - 0.5 x 2.5 = 1.25

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

lb medium onion, diced - 1 x 2.5 =

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

**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
