Mnenie [13.5K]3 years ago

Answer:

\bold{x = \dfrac{8}{9}}

Step-by-step explanation:

We have to rewrite the below as simplified fraction.

\large{0.\overline{8} = {?}}

Solution:

Let x =0.\overline 8 which means x =0.888888.......

Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.

To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.

So, we can rewrite x as:

x =0.8\overline8 ......(1)

Now, let us multiply the above with 10.

10x = 0.8\overline 8 \times 10\\\Rightarrow 10 x= 8.\overline8 ....... (2)

Now, let us subtract (1) from (2):

10x-x=8.\overline8 - 0.\overline8\\\Rightarrow 9x = 8\\\Rightarrow \bold{x = \dfrac{8}{9}}

So, in simplified fractions:

\large{0.\overline{8} =  \bold{\dfrac{8}{9}}}

The change in the value of an account when given to the nearest dollar?
devlian [24]
What changes may occur if the given dollar will be rounded off to its nearest value.
<span>There will only be 2 chances, the dollar will become smaller or bigger. Why? </span>
Because in mathematical rules of rounding off numbers:
number below 5 will be round down and 5 and up will be rounded up.
For example:
You have a bill of $6.79  since the number next to the decimal point in the right is 7, it will be rounded up to $7.
<span>But if your bill is $6.25, it will be rounded down to $6.00
