Explain how scaling a mixed number by 1/2 will affect the size of a number

Answers

Answer 1

Answer: If the mixed number is scaled by 1/2 then, the original number will be divided by 2. That being said, the number then becomes 50% of the original value. Hence, scaling the number by 1/2 will make the number only 50% of its original value.

grant starteda marathon at 8:00 A.M. he took 4 hours 49 minutes to complete the marathon. when did he crosd the finish line

Answers

If he starts at 8:00 AM and you start counting up by 1 hour at a time...

8:00 - 9:00 = 1 hour
9:00 - 10:00 = 1 hour
10:00 - 11:00 = 1 hour
11:00 - 12:00 = 1 hour

So far that is 4 hours that have passed and we are up to 12:00. Now remember, when we reach 12:00 we switch from AM to PM (that's 12 noon).

We only have 49 minutes left so now we just add that in

12:49 PM is when he crossed the finish line.
