Lucas took his bike to a local park to ride on some bike trail.Trail A is 6 3/4 miles long.Trail B is 8 1/2 miles long. How many
Eddi Din [679]

Answer: Trial B is 1\dfrac{3}{4} miles longer then Trail A.

Step-by-step explanation:

Length of Trail A = 6\dfrac34 miles

= \dfrac{24+3}{4}  miles = \dfrac{27}{4} miles.

Length of Trail B = 8\dfrac12 miles

= \dfrac{16+1}{2} miles = \dfrac{17}{2} miles.

Trial B is longer then Trail A by \dfrac{17}{2}-\dfrac{27}{4} miles

=\dfrac{17\times2}{2\times2}-\dfrac{27}{4} miles

=\dfrac{34}{4}-\dfrac{27}{4} miles

=\dfrac{7}{4} miles

=1\dfrac{3}{4} miles

Hence, Trial B is 1\dfrac{3}{4} miles longer then Trail A.
