what is an improper fraction for 8.2

Question

joe went running 3 days. he ran 2.5 miles on monday, 2 3/10 on Wednesday and 3 2/5 on friday. how far did joe run altogether?

Answer 1

0.2 would be read as "two-tenths," so that would be the fraction... well. two-tenths: ²/₁₀.

Since the numerator and denominator have a 2 in common, that can be factored out: ¹/₅.

 

So you know have the mixed number 8 ¹/₅. To make it an improper fraction, you just need to convert that 8:

⁸/₁ * ⁵/₅, then add the ¹/₅ to that for your final answer.
