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

soldier1979 [14.2K]

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.

Can somebody help me out? I’ll mark as brainliest.

Answer:

f(x) = -5x - 14

Step-by-step explanation:

this table represent a straight line : y = mx +c

first find m which is the slope

m = (-24 - -19)/(2-1) = -5

then find c

-19 = -5(1) + c , c = -14

thus f(x) = -5x -14
