What is the decimal representation of 5/11

Answers

Answer:

$(5)/(11)=0.\overline{45}$

Step-by-step explanation:

Given: $(5)/(11)$

We need to change given fraction into decimal.

$x=(5)/(11)-------(1)$

$11x=5$

Multiply both sides by 9

$99x=45-----------(2)$

Add equation (1) and (2)

$99x+x=45+(5)/(11)$

$100x=45.45.....$

Divide both sides by 100

$x=0.454545.....$

$(5)/(11)=0.454545.......=0.\overline{45}$

0.45 is the answer but
0.45454545454is it
