Answer:

a. 11/15

b. 4/15

Step-by-step explanation:

a. we need to add monday with Tuesday so we need to make the denominators equal

we can do that by making them both 15

so monday is already 15

and in Tuesday we can do that by multiplying 5 by 3 and we also need to multiply 3 by 3

so Tuesday becomes 9/15

then we add 2/15 + 9/15 = 11/15

b. we need to find what's left so we subtract 15/15 - 11/15 = 4/15
