Write 2/15 as a decimal.

Cloud [144]

If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:
$\frac{2}{15} = \frac{x}{10}$

now let's multiply both sides by 10:
$\frac{20}{15} = x$
and simplyfy:
(by dividing the first fraction's elements by 5)
$\frac{4}{3} = x$

change improper fraction into a mixed number
$1\frac{1}{3} = x$

and 1 over 3 is 0.33333...

so the answer is 1.333333 - we can also write it as 1.(3)

kondor19780726 [428]

<u>Step-by-step explanation:</u>

Co-ordinates = (4,8) & (-9,5)

Slope (m) = (y² - y¹) / (x² - x¹)

(m) = (5 - 8) / (-9 - 4)

(m) = -3 / -13

(m) = 3 / 13

Equation => y = mx + c
