you just divide 50[tex] \frac{1}{4} [/tex] or [tex] \frac{201}{4} [/tex] by 4[tex] \frac{1}{8} [/tex] or [tex] \frac{33}{8} [/tex]
soo lets divide!
first you get the reciprocal of the 2nd fraction
then multiply
and just simplify if needed
[tex] \frac{201}{4} [/tex]÷[tex] \frac{33}{8} [/tex]
now just multiply instead of dividing resulting to:
[tex] \frac{134}{11} [/tex] ≈12.18181818...
