Alexia ran three laps around her neighborhood. Each lap is 1 and StartFraction 3 over 8 EndFraction miles. Which is the best estimate of the number of miles that Alexia ran? 2 miles
3 and one-half miles
4 and one-half miles
6 miles

4 and one-half miles

Step-by-step explanation:

The answer closest to the correct answer is 4 and one-half miles.

To get the answer, you multiply 3 times the length of one lap which is 1 and miles.  To multiply the fraction, you take 3 times the top number in the fraction.  So 3 x 1 = 3 .  The fraction can actually be reduced to 1 and miles.  So you're total correct answer is 4 and miles.

The second selection is 3 and which can also be written as 3 and to make it easier to determine which answer is correct.  The second answer is therefore shorter than the correct answer.

The third selection is 4 and which can be written as 4 and so it is only longer than the correct answer.  So this selection is the closest to the actual miles ran.

okay so 15.15 *()5: +5/6
