Answer 1

Answer:

3 3/4 tablespoons of coffee to make 10 cups of coffee

 

3 3/4 =15/4

 

10 cups require 15/4 tablespoon of coffee

1 cup require how much

 

15/4 divide by 10

 

15/4 ÷ 10

=15/4 * 1/10

=15/40

=3/8  tablespoon of coffee for 1 cup of coffee

Answer 2

Answer:

3/8 Tablespoon per cup

Step-by-step explanation:

Our unit rate here is

3  3/4 Tablespoons

-----------------------------

    10 cups coffee

Converting 3  3/4 to an improper fraction, we get 15/4 Tablespoons:

15/4 Tablespoons          15

---------------------------  =  -------- Tablespoons/cup

 10 cups coffee              40

Reduce this by dividing numerator and denominator both by 5:

3/8 Tablespoon per cup
