What is 4 1/3 × 2 3/5? express it in lowest terms

We have,

$4\dfrac{1}{3}\cdot2\dfrac{3}{5}=\dfrac{13}{3}\cdot\dfrac{13}{5}=\dfrac{13\cdot13}{3\cdot5}=\dfrac{169}{15}=\boxed{11.2\bar{6}}$

To express periodic number calculated we use:

$x=11.2\bar{6}\\10x = 112.\bar{6}\\100x=1126.\bar{6}\\90x=100x-10x\Longrightarrow90x=1126.\bar6-112.\bar6\\90x=1014\\x=\dfrac{1014}{90}=\boxed{11\dfrac{24}{90}}$

Hope this helps.

Anybody...Help!!!!!!!!!!!

Simple...

when they ask for the rate of change they ask for slope -->>

Using $\frac{ y_{1} - y_{2} }{ x_{1} - x_{2} }$ to find the rate of change for (-3,0) and (-2,-5)

$\frac{0--5}{-3--2}$

$\frac{0+5}{-3+2}$

$\frac{5}{-1}$

m=-5

Thus, your answer.

Charra [1.4K]

I think the answer is 12.6 extra gigabytes because:

20 - 51.50 = 31.50

31.50 / 2.50 = 12.6

Julio believes that the quotient of 6 divided by 1/2 = 3. Explain Julios error and tell how to find the correct answer.

Gnom [1K]

Answer:

it can be written as 6/1 divided by 1/2

then you'll use the keep, switch, flip method. keep 6/1, switch division to multiplication, and flip 1/2 to become 2/1 or 2

now your equation is 6 x 2 = 12

Julio did 6 divided by 2. which could've been fixed if he changed the division sign to multiplication and multiplied
