Answer:

5/9

= 55.56% ( to the nearest hundredth).

Step-by-step explanation:

The total number of little squares in the large square = 6*6 = 36.

Total number of shaded squares = 2*6 + 2*4

= 12 + 8 = 20.

So the fraction of shaded part

= 20/36

= 5/9.

As a percentage this is 5*100/9

= 55 5/9%

= 55.55..... %

Answer:

$\frac{20}{36}$

Step-by-step explanation:

the total amount of squares within this square is 36

and the number of shaded squares would be 20

so if 20 squares out of 36 squares are shaded, then the fraction is

$\frac{20}{36}$

or 55.56%

(to find percentage multiply $\frac{20}{36}$ by 100)

Whats the answer to that question?

Answer:

-0.9090... can be written as $\frac{10}{11}$ .

Explanation:

Any repeating decimal can be written as a fraction by dividing the section of the pattern to be repeated by 9's.

We can start by listing out

0.909090... = 9/10 + 0/100 + 9/1000 + 0/10000 + 9/100000 + 0/1000000 + ...

Now. we let this series be equal to x, that is

$x$ = 9/10 + 0/100 + 9/1000 + 0/10000 + 9/100000 + 0/1000000 + ...

Now, we'll multiply both sides by 100 .

$100x$ = 90 + 0 + 9/10 + 0/100 + 9/1000 + 0/10000 + ...

Then, subtract the 1st equation from the second like so:

$100x$ = 90 + 0 + 9/10 + 0/100 + 9/1000 + 0/10000 + 9/100000 + 0/1000000 + ...

$-x$ = - 9/10 - 0/100 - 9/1000 - 0/10000 - 9/100000 - 0/1000000 - ...

And we end up with this:

$99x=90$

Finally, we divide both sides by 99 in order to isolate x and get the fraction we're looking for.

$x=\frac{90}{99}$

Which can be reduced and simplified to

$x=\frac{10}{11}$

Hope this helps!
