Answer:
c
Step-by-step explanation:
1) add up all the hours :
(Monday + Tuesday + Wednesday + Thursday + Friday = ? )
[tex]\frac{3}{4} + 1\frac{1}{6} + \frac{1}{2} + 1\frac{1}{3} + 2 = \\\\\frac{9}{12} + 1\frac{2}{12} + \frac{6}{12} + 1\frac{4}{12} + 2 =\frac{9}{12} + 5[/tex]
[tex]5 + \frac{9}{12} = \frac{60}{12} + \frac{9}{12} = \frac{69}{12}[/tex] => ?
2) minus the ''?'' with the total hour
[tex]9\frac{1}{4} - \frac{69}{12} = \frac{37}{4} - \frac{69}{12}=\\[/tex]
[tex]\frac{37}{4} = \frac{111}{12} \\\\\frac{111}{12} - \frac{69}{12} = \frac{42}{12}[/tex]
42/12 => simplfy with 6 => 7/2 = 3 1 by 2
Hope this helps ^-^
