<u>Answer</u>

\frac{7}{37}


<u>Detailed Explanation </u>

To simply answer this, since .189 has three digits we are going to be inserting 999 as the denominator since it is a repeating decimal.


\frac{189}{999}


We could simplify the answer!

\frac{189}{999}


Therefore, the answer would simply be \frac{7}{37}

\frac{7}{37}


<u>Always Remember </u>

In the future, always remember whenever you have a three digit decimal and the problem asks you to convert it into a fraction, you should always insert 1000 as the denominator (the numerator is basically the decimal without the decimal point) and simplify if necessary.

x=0.\overline{189}\\ 1000x=189.\overline{189}\\ 1000x-x=189.\overline{189}-0.\overline{189}\\ 999x=189\\ x=\dfrac{189}{999}=\dfrac{7}{37}

-----------------------------------
or using this weird notation
x=0.\dot{1}8\dot{9}\\&#10;1000x=189.\dot{1}8\dot{9}\\&#10;1000x-x=189.\dot{1}8\dot{9}-0.\dot{1}8\dot{9}\\&#10;999x=189\\&#10;x=\dfrac{189}{999}=\dfrac{7}{37}

What is the area of the figure?
Mrrafil [7]

Answer:

The shape has a total area of 14.96cm²

Step-by-step explanation:

To solve this all you need to do is take the area of the outer rectangle, and subtract the area of the inner rectangle.

The outer rectangle is 5.6 by 6.4 cm.  To get its area, just multiply those dimensions. When you do so you get the area 35.84cm².

Next the inner rectangle needs to be subtracted.  First though, we need its width, which we're not directly given.

We do however know the width of the entire shape, and the width of segments left after cutting out the inner rectangle.  All we need to do then is subtract the later from the former to the the inner rectangle's width:

5.6cm - 1.2cm - 0.8cm = 3.6cm

Great!  The inner rectangle has an area of 3.6cm × 5.8cm.  That gives us 20.88cm².

The final step is to subtract that 20.88 square cm from the 35.84 that we already have.  Doing so gives us a result of 14.96cm², and that is the final answer.
