Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are: [tex]$ \frac{5}{8} $[/tex] and [tex]$ \frac{8}{10} $[/tex].
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions [tex]$ \frac{p}{q} $[/tex] and [tex]$ \frac{x}{y} $[/tex].
We say they are proportional if [tex]$ p : q = x : y $[/tex].
Or, if [tex]$ py = qx $[/tex] then we can say the fractions are proportional.
Here the fractions are: [tex]$ \frac{5}{8} $[/tex] and [tex]$ \frac{8}{10} $[/tex].
LHS: 5 X 10 = 50.
RHS: 8 X 8 = 64.
Clearly they are not equal. So, we can say these two fractions are not proportional.
