For this case we must simplify the following expressions:
Option A:
[tex]\frac {12} {18} = \frac {6} {9} = \frac {2} {3}[/tex]
We divide numerator and denominator by 2 and then by 3.
Option B:
[tex]\frac {48} {54} = \frac {24} {27} = \frac {8} {9}[/tex]
We divide numerator and denominator by 2 and then by 3.
Option C:
[tex]\frac {27} {90} = \frac {9} {30} = \frac {3} {10}[/tex]
We divide numerator and denominator by 3 and then by 3 again.
Option D:
[tex]\frac {63} {77} = \frac {9} {11}[/tex]
We divide numerator and denominator by 7.
Option E:
[tex]\frac {24} {32} = \frac {12} {16} = \frac {6} {8} = \frac {3} {4}[/tex]
We divide numerator and denominator three times by 2.
Option F:
[tex]\frac {73} {365} = \frac {1} {5}[/tex]
We divide numerator and denominator by 73.
Answer:
[tex]\frac {2} {3}\\\frac {8} {9}\\\frac {3} {10}\\\frac {9} {11}\\\frac {3} {4}\\\frac {1} {5}[/tex]
