You will need to divide the numerator and the denominator by the same number:

[tex] \dfrac{20}{30} = \dfrac{20 \div 5}{30 \div 5} = \dfrac{4}{6} = \dfrac{4 \div 2}{6 \div 2} = \dfrac{2}{3} [/tex]
You have to divide the top (numerator) and bottom (denominator) by the same number.
For this fraction you need to divide by 10. So the correct simplified fraction would be 2/3
