<span>Well, think of it this way? How many times does 5 go into 9?
5 * 1 = 5
5 * 2 = 10
So 5 goes into 9 one time. Then you have to subtract that 5 from 9 to be left with your fraction value.
1 and 4/5 is your mixed number.</span>
Answer:
Event D
Step-by-step explanation:
Complementary events are those events that are opposites of each other. i.e. in this case the complementary event for choosing a green marble is not choosing a green. It has nothing to do with choosing or not choosing marbles of colors other than green.
You can round 976 to 1000 and 522 to 500. So it would be
1000 - 500 = 500. The answer you would get after subtracting 976-522 would be more than 400 if you round it.

the fractions are set up so that each unit cancels out until its only meters/hour
you can multiply all the numerators together to get 72000 and all the denominators to get 1
72000 meters/1 hour
72000 meters in 1 hour
hope this helped
