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

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

X plus 1/3 equals nine enter your answer in the box in simplest form

LekaFEV [45]

$= > x + \frac{1}{3} = 9$

$\text{Add} \: - \frac{1}{3} \: \text{ on both sides ,}$

$= > x + \frac{1}{3} - \frac{1}{3} = 9 - \frac{1}{3} \\ \\ \\ \\ = > x = \frac{(9 \times 3) - 1}{3} \\ \\ \\ \\ = > x = \frac{27 - 1}{3} \\ \\ \\ \boxed{ \bold{= > x = \frac{26}{3} }} \\ \\ \\ or , \boxed{ \bold{ \: x = 8. \bar{6}}}$

Hence,

$Value \: \: \: of \: \: x \: \: is \: \frac{26}{3} \: \: \: or \: \: \: 8. \bar{6}$
