Start by simplifying both fractions
[tex]
\dfrac{24}{32}=\dfrac{12}{16}=\dfrac{6}{8}=\dfrac{3}{4} \\
\dfrac{48}{64}=\dfrac{24}{32}=\dfrac{12}{16}=\dfrac{6}{8}=\dfrac{3}{4}
[/tex]
As you can see both fractions simplify to a same value hence the equality
[tex]\dfrac{24}{32}=\dfrac{48}{64}[/tex]
stands.
Hope this helps.
