Answer:

34

Explanation:


(2)/(5)*85

Long way

  1. multiply the two numerators
  2. multiply the two denominators
  3. simplify the new fractions


(85)/(1)*(2)/(5) \\ \\ (170)/(5) \\ \\ =34

short way

-can be simplified before mulitplying

  1. factor out common factors in the numerator and denominator


(85)/(1) *(2)/(5) \\ \\ (17)/(1)*(2)/(1) =34

Think 85 and 5 as nickels. You need 20 nickels to make 100. Subtract 100 by 85 to get 15. You get 3 nickels and 17 nickels. 17 is the common factor. Multiply 17 by 2 to get your answer.
