To express the fraction \( \frac{20}{80} \) in the form \( \frac{?}{?} \), we can simplify it.
First, we can simplify \( \frac{20}{80} \) by dividing both the numerator and the denominator by their greatest common divisor, which is 20:
\[ \frac{20 \div 20}{80 \div 20} = \frac{1}{4} \]
Thus, \( 20/80 = 1/4 \).
To express this in the form \( \frac{?}{?} \), you can represent it as \( \frac{1}{4} \) or choose any other equivalent fractions. For example:
\[ \frac{2}{8}, \quad \frac{5}{20}, \quad \frac{10}{40}, \quad \frac{25}{100} \]
These all represent the same ratio as \( \frac{20}{80} \).
So, one possible answer is:
\[ \frac{1}{4} = \frac{?}{?} = \frac{1}{4} \]
Alternatively, if you want two numbers, it can be \( \frac{2}{8} \), for example.
