ariana has 2/3 quart of milk. she uses 3/4 of it in a recipe. how much milk did ariana use in her recipe?

Answers

To find a fraction of a fraction, what you have to do is multiply. You're looking for $(3)/(4)$ of $(2)/(3)$ so you're equation is going to be

$(3)/(4)$ × $(2)/(3)$ =

To multiply fractions, you multiply straight across (numerator x numerator, denominator x denominator):
$(3)/(4)$ × $(2)/(3)$ = $(6)/(12)$ quart or $(1)/(2)$ quart

This makes more sense when you draw a picture. First starting by drawing what you're taking a fraction of, which is $(2)/(3)$ . Then you split the entire whole into fourths to find what $(3)/(4)$ is. See the attached picture. :)

She has 2/3 quart and only used 3/4 of it.

If she had used twice as much, you'd multiply by 2, but instead, she used only 3/4 of it, so you'll only need to multiply her amount by 3/4, like so:

2/3*3/4 = (2*3)/(3*4) = 6/12 = 1/2

Answer is: 1/2 quart

What is the average of something (mean or mode) I really need to know I forgot what the difference was ho

Answers

The mean is the average, or when you add all the numbers and divide it by how many numbers there are. And the mode is how frequently some number appears in a set of numbers. (For example- 1,1,1, 4,9,1,6,13,6 ---> the mode is one.)

The difference between mean and mode is that mode is the number that shows up most often and the mean is all the numbers add up then divided by how ever many numbers you added

5.4(m-2)= -2(3m+3) please help asap

Answers

Answer:

m = 0.421

Step-by-step explanation:

5.4(m-2)= -2(3m+3) (expand parentheses by distributive property)

m(5.4) -2(5.4) = 3m(-2) + 3(-2)

5.4m - 10.8 = -6m - 6 (add 6m to both sides)

5.4m - 10.8 + 6m = - 6

11.4m - 10.8 = - 6 (add 10.8 to both sides)

11.4m = -6 + 10.8

11.4m = 4.8 (divide both sides by 11.4)

m = 4.8 / 11.4

m = 0.421

Answer:

m = 8/19

Step-by-step explanation :

5.4 (m-2) = -2 (3m +3)

54/10 (m-2) = (3m +3) as n = 1

2.3^3 / 2.5 (m-2) = (3m + 3)

4.868 (m-2) = (3m +3)

4.868 + 3 = (3m^2 * m-2)

8 / 9.5 * 2

m = 8 / 19
