OpenStudy (anonymous):

40

OpenStudy (goldphenoix):

Nope. You basically switch the number around. So the reciprocal of 5/8 is 8/5. So 5/8 * 8/5 = ?

OpenStudy (anonymous):

40/40

OpenStudy (goldphenoix):

Which simplify to 1. Great, so on the left side of the equation we have 1n or just n. But since we multiply 8/5 to one side of the equation, then we must do it to the other side of the equation. 1/4 * 8/5 = ?

OpenStudy (anonymous):

8/20

OpenStudy (anonymous):

OpenStudy (goldphenoix):

Simplify it. What is a common factor of 8 and 20?
