### Sierra's Rate Growing Post

Rate- compares 2 quantities measured in different units.

Ratio- compares 2 quantities measured in the same units.

What is the difference between ratio and rate?
Rate is comparing 2 quantities measured in different units, when a ratio compares 2 quantities in the same unit.

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

All you have to do to find a serving amount for 10 people instead of 4, is to multiply all the original numbers by 2.5.

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.
To find out how much ingredients you need for a serving for 1 person, since you already have the calculations for the serving for 10 people, just divide those answers, and whatever it equals to, that's the amount of stuff you need for a serving of 1 person.

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

Good Job! Showing your work is important to show that you fully understand a problem and how to get the answer.
