Tracy has 7/8 pounds of butter in her refrigirator. She uses 2/3 of it for cookie batter. How much of the butter did she use?
adelina 88 [10]

Answer:

16/24

Step-by-step explanation:

So you need to get a common denominator before you try to answer the whole question. Turn the denominator into 24. Since you would multiply 8 by 3, multiply the 7 by 3. That would make 21/24. Make the 3 a 24, multiplying it by 8 and doing the same to the 2 making 16/24.

Use the inverse variation equation to fill in the table.
Mandarinka [93]

The value of a is  0.10.

The value of b is 20.78.

The value of c is 0.02.

<h3>What are the missing values?</h3>

When two variables have inverse variation, the two variables move in opposite directions. If one variable increases, the other decreases.

p = 8.31 / V

V = 8.31 / p

a = 8.31 / 83.1 = 0.10

b = 8.31 / 0.4 = 20.78

c = 8.31 / 415.5 = 0.02

Ganezh [65]

Answer: See explanation

Step-by-step explanation:

Your question isn't clear but let me help out by reframing the question .

Let's say that Mr. Jones bought 5kilograms of flour for $825. To get the price of a kilogram of flour, we will need to divide $825 by 5. This will be:

= $825 / 5

= $165

Therefore, the price of a kilogram of flour will be $165
