Answer:6 17/18 hours
Step-by-step explanation:
We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.
The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:
= 2 1/6 + 4 7/9
= 2 3/18 + 4 14/18
= 6 17/18
She used a total of 6 17/18 hours studying
Look at the factors in the 5 numbers. there are 3 factors, and each
number is the product of 2 of them (or 1 of them, twice). There is one
"pair" missing. Hope this helps!!!
