47.78% is the government's approval rating (this is rounded, it is really 47.777repeating)
Hello :
0.45 = 45/100 = 9/20
Solution
Simplifying the Complex Fraction
<span><span><span>23</span><span>13</span></span><span><span>23</span><span>13</span></span></span>
Method 1 : LCD Multiplication
The LCD for 3 and 3 is 3
Multiply top and bottom by the LCD<span><span><span><span>3×<span>23</span></span><span>3×<span>13</span></span></span>=<span>21</span></span><span><span><span>3×<span>23</span></span><span>3×<span>13</span></span></span>=<span>21</span></span></span>
convert to mixed numbers and
reduce fractions where possible
<span><span>=2</span><span>=2</span></span>
Method 2 : Fraction Division
Divide the top fraction by the bottom
(multiply top by reciprocal of bottom)
<span><span><span>23</span>÷<span>13</span></span><span><span>23</span>÷<span>13</span></span></span><span><span>=<span>23</span>×<span>31</span></span><span>=<span>23</span>×<span>31</span></span></span><span><span>=<span>63</span></span><span>=<span>63</span></span></span>
convert to mixed numbers and
reduce fractions where possible
<span><span>=<span>63</span>=<span>21</span>=2
