Question

write the ratio as a fraction in lowest terms.
7 days to 19 days

Explanation:

Step1: Define the ratio as a fraction

The ratio of 7 days to 19 days can be written as the fraction $\frac{7}{19}$.

Step2: Check if it can be simplified

To check if $\frac{7}{19}$ is in lowest terms, we find the greatest common divisor (GCD) of 7 and 19. The factors of 7 are 1 and 7, and the factors of 19 are 1 and 19. The only common factor is 1, so the fraction cannot be simplified further.

Answer:

$\frac{7}{19}$
