riemer's rate growing post


PART 2 ! :)


Ratio:where you poop then compare two quantities measured in the same unit
Rate:where you poop then compare two quantities measured in different units



The difference between ugly ratio and rate is that ratio compares two quantities are measured in the same unit and rate compares two quantities measured in different units.

Determine the unit rate in each situation.

a) An orca swims 110 km in 2 h.
55/hour

b) A Canada goose flies 800 km in 12.5 h.
19.3/hour

c) Cathy plants 45 daffodils in 30 min.
1.5/mins.

Trevour rode his mountaion 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 ?

Trevour: divide each side by 3 which then gives you 28 km/h.
Jillian: divide each side by 2.5 which gets you the same answer 28 km/h.

They are both going the same speed, that means that neither cyclists are faster.
 

PART 2 ! :)


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



I just divided poop 10 by 4 .


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


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
