The lowest common denominator is $10$.

Explanation:

To calculate the lowest common denominator of 2 fractions you multiply their denominators and divide the result by their greatest common divisor.

Since $2$ and $5$ are prime numbers their only common divisor is $1$, so the lowest common multiplier is $2 \cdot 5 = 10$
