Eduardo biked 2.57 miles to the library and then 1 1/8 miles to a
friend’s house. which is the most reasonable estimate for the
total distance eduardo biked?
1.5 miles
2 miles
3.5 miles
6 miles

3.5 miles

Step-by-step explanation:

We need to convert the fraction into decimal and add up both in decimal form and then make our estimate (closest to the exact answer).

1 and 1/8th means 1.SOMETHING

Dividing 1 by 8 would give us:

1/8 = 0.125

Hence, 1  1/8th = 1.125

Total miles = 2.57 + 1.125 = 3.695

THis is closes to 3.5 miles. THis is the answer.

NOT every rational number is a whole number
