Answer:
(Any could be possible answers)=> 11/6 hours, 1 5/6 hours, 1 hour and 50 minutes.
Step-by-step explanation:
Ok, let's set up a system here.
Let kitchen = 1/3 hours
Let laundry = 1 1/2 hours
The question is asking that we need to add all together the support that Matthew was doing during cleaning the kitchen and help with laundry.
So, technically it's going to result in this:
Kitchen + Laundry = Hours together
So, you plug it in with it's definition, and simply solve it:
1/3 + 1 1/2 = Hours Together
1/3 + 3/2 = Hours together
2/6 + 9/6 = Hours Together
11/6 = Hours together
