1) 2 1/3 is also equal to 7/3
4 1/5 is also equal to 21/5
you need to make the denominators the same so you have to find the lowest common multiple, which is 15 since both 5 and 3 can be times by to make 15
you need to also times the numerators by the number you're timesing the denominator by
7/3 x 5 = 35/15
21/5 x 3 = 63/15
now add those together
35/15 + 63/15 = 98/15
now just convert 98/15 back to a mixed fraction
98/15 = 6 8/15
the answer is..

I'll do the others in a different answer!!

Answer:
D Malin ran from 3:42 PM until 4:17
Step-by-step explanation:
You need only examine the least-significant digits to determine of the difference of times will end in 5.
The only time difference that is 35 minutes is ...
3:42 pm to 4:17 pm . . . . . . choice D
The answer is 336 because since combinations are a way to calculate the total calculations so the answer is 336.
There needs to be a picture of the whole worksheet for me to answer. But you can go to the website at the bottom of the sheet and most likely find a answer key.
