How many=x twentieth=1/20 are in= = five halves= 5/2
1/20x = 5/2 [tex] \frac{1}{20}x= \frac{5}{2} [/tex]5/2 First we must get rid of the denominator. Find the LCD. [tex] 20\left[\begin{array}{ccc} \frac{1}{20}x= \frac{5}{2} \end{array}\right] [/tex]
x=50 To check, plug 50 into the original equation. [tex] \frac{50}{20}= \frac{5}{2} [/tex] So it checks out.
