Step-by-step explanation:
Distance = positive value
a + a = 2a
Answer:
Explanation:
The expression that must be rewritten as a fully simplified fraction is:
You must, first, convert
as a fraction.
The line over the decimal 4 means that the digit 4 repeats indefinetly.
To find the fraction that represents this number you follow this procedure:
![F=0.\overline 4\\ \\ 10F=4.\overline 4\\ \\ 10F-F=4\\ \\ 9F=4\\ \\ F=4/9](https://tex.z-dn.net/?f=F%3D0.%5Coverline%204%5C%5C%20%5C%5C%2010F%3D4.%5Coverline%204%5C%5C%20%5C%5C%2010F-F%3D4%5C%5C%20%5C%5C%209F%3D4%5C%5C%20%5C%5C%20F%3D4%2F9)
Now, you can mutiply both fractions:
![\frac{99}{100}.\frac{4}{9}=\frac{99\times 4}{100\times9}=\frac{11}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B99%7D%7B100%7D.%5Cfrac%7B4%7D%7B9%7D%3D%5Cfrac%7B99%5Ctimes%204%7D%7B100%5Ctimes9%7D%3D%5Cfrac%7B11%7D%7B25%7D)
The 2nd option is the answer :)!
