Answer:

3 1/12 hours

Step-by-step explanation:

Add the hours for Tuesday and Wednesday to find the total hours

1 3/4 + 1 1/3

We need to find the common denominator of 12

1 3/4*3/3    + 1 1/3 *4/4

1 9/12   + 1 4/12

2 13/12

2 + 12/12 +1/12

2+1+1/12

3 1/12

Rewrite the fractions so they have a common denominator:

3/4 = 9/12

1/3 = 4/12

Now you have 1 9/12 + 1 4/12

Add together to get 3 1/12 hours
