EEEYYYOO I'M RICOOO.

Part one

Definitions:

Rate- measures two different quantities measures in the same unit.

Ratio- Compares two quantities measured in different units.

What is the difference between a ratio and rate?

A Rate is comparing two quantities measured in different units, and a Ratio compares 2 quantities in the same unit.

6. Gina earns $78.00 for working 6 h. Asad makes $192.50 after working 14 h. Determine each person's unit rate of pay. Who has a greater hourly rate of pay?

Gina: $78/6h = 13/1h Gina gets $13 an hour.

Asad $ 192.50/14 = $13.75/1h Asad gets 13.75 an hour.

Asad gets more pay than Gina.

10. Trevor rode his mountain bike 84 km in 3 hours. Jillian rode her mountain bike 70 km in 2.5 hours. Who is the faster cyclist ?. How do you know ?

Trevor: 84/3 = 28km/hour.

Jillian: 70/2.5 = 28 km/hour.

So that means they were both going the same speed.

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

Ground beef - 0.5 x 2.5 = 1.25 lb

Medium Onion diced - 1 x 2.5 = 2.5

Stalked celery finely diced - 1 x 2.5 = 2.5

Clove garlic minced - 1 x 2.5 = 2.5

Canned tomatoes chopped - 14 oz x 2.5 = 35 oz

Canned 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 - o.5 x 2.5 = 1.25 tsp

Seasoning Salt - o.5 x 2.5 = 1.25 tsp

Bay leaf - 1 x 2.5 = 2.5

2. What would the recipe look like if it only had to serve 1 person. Show your work.

Ground beef - 1.25 ÷ 10 = 0.125 lb

Medium Onion diced - 2.5 ÷ 10 = 0.25

Stalked celery finely diced - 2.5 ÷ 10 = 0.25

Clove garlic minced - 2.5 ÷ 10 = 0.25

Canned tomatoes chopped - 35 oz ÷ 10 = 3.5 oz

Canned 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

What I did is divide it all by 10 to get 1.
