How to do 3 4/5 ÷ 1 1/3

andrew11 [14]

Answer: 2 7/15

Step-by-step explanation: First, you make sure you have the same denominator on both of the fractions.

4/5 turns to 12/15 and 1/3 turns to 5/15

After that, then you do 12/15 - 5/15, which is 7/15.

Now you do 3 - 1.

Your answer should be 2 7/15.

I hope this helps you and I hope you have a blessed day!

Answer:

The inequality $\frac{8}{4}\:$ is true.

Step-by-step explanation:

Given

$\frac{8}{5}$

FALSE

Reason: 8/5 or 1.6 is greater than 9/10 or 0.9

$1>\frac{6}{5}$

FALSE

Reason: 1 is smaller than 6/5 or (1.1)

$\frac{5}{2}$

converting mixed number to improper fraction

$\frac{5}{2}$

FALSE

Reason: 5/2 can not be less than 5/2

$\frac{8}{4}\:$

$2$

TRUE

Reason: 2 is indeed smaller than 5/2 or 5.2 ∵ 5/2 = 2.5

Therefore, inequality $\frac{8}{4}\:$ is true.

X^3 + 8 = (x+2)(____)<br> What do I have to multiply by (x+2) to get x^3 + 8

sasho [114]

x² - 2x + 4
x + 2|x³ + 0x² + 0x + 8
x³ + 2x²
-2x² + 0x
-2x² - 4x
4x + 8
4x + 8
0

x³ + 8 = (x + 2)(x² - 2x + 4)
x³ + 8 = (x + 2)(x - 2)(x - 2)
x³ + 8 = (x + 2)(x - 2)²
