Can someone plis help me​

Answer 1

Answer:

c

Step-by-step explanation:

1) add up all the hours :

(Monday + Tuesday + Wednesday + Thursday + Friday =  ? )

$\frac{3}{4} + 1\frac{1}{6} + \frac{1}{2} + 1\frac{1}{3} + 2 = \\\\\frac{9}{12} + 1\frac{2}{12} + \frac{6}{12} + 1\frac{4}{12} + 2 =\frac{9}{12} + 5$

$5 + \frac{9}{12} = \frac{60}{12} + \frac{9}{12} = \frac{69}{12}$ => ?

2) minus the ''?'' with the total hour

$9\frac{1}{4} - \frac{69}{12} = \frac{37}{4} - \frac{69}{12}=$

$\frac{37}{4} = \frac{111}{12} \\\\\frac{111}{12} - \frac{69}{12} = \frac{42}{12}$

42/12 => simplfy with 6 =>  7/2 = 3  1 by 2

Hope this helps ^-^
