Question

Lori is running a marathon, which is 26.2 miles long. So far, she has run one-tenth of the marathon. How far has Lori run? (from the book)

Answer 1

She has 23.58 miles left to run because you multiply 26.2×0.1 and get 23.58.

Answer 2

to find how long Lori has run do 1/10 x 26.2
1/10 x 131/5
= (1x131) / (10x5)
= 131/50 or 2 and 31/50 miles long
