Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are: and
.
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions and
.
We say they are proportional if .
Or, if then we can say the fractions are proportional.
Here the fractions are: and
.
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.
