evaluate each expression 'four over fivex for x = five over eight

OpenStudy (anonymous):

I have the other 5 questions answered all I need is this one

OpenStudy (mathmale):

\[Evaluate \frac{ 4 }{ 5x } where x=\frac{ 5 }{ 8 }\]

OpenStudy (anonymous):

the answers to choose from is 2, 1/2 and 1/4

OpenStudy (mathmale):

Let's now substitute 5/8 for x:\[\frac{ 4 }{ 5(\frac{ 5 }{ 8 }) }=\frac{ 4 }{ \frac{ 25 }{ 8 } }=\frac{ 4 }{ 1 }*\frac{ 8 }{ 25 }=?\]

OpenStudy (mathmale):

Reminder: To divide 4 by the fraction 25/8, invert the 25/8 and MULTIPLY 4 by that. OK?

OpenStudy (mathmale):

Please finish the problem by multiplying the two fractions together. Best wishes to you!
