To find a fraction equivalent to \( \frac{20}{10} \), you can simplify it first.
\[ \frac{20 \div 10}{10 \div 10} = \frac{2}{1} \]
If you need to fill in the blank so that it forms a fraction equivalent to \( \frac{20}{10} \) with the denominator being 2, you would do the same operation:
The equivalent fraction would be \( \frac{20}{10} = \frac{x}{2} \).
To solve for \( x \):
\[ \frac{20}{10} = \frac{x}{2} \implies 20 \times 2 = 10x \implies 40 = 10x \implies x = 4 \]
So, the fraction is \( \frac{4}{2} \), which is equivalent to \( \frac{20}{10} \).
Therefore, the blank can be filled with:
4:2
