Let's create that into a math equation
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.
