Compare the fraction 1:24,000 to the fraction 1:3,168,000; which is the largest rational number
gulaghasi [49]

Answer:

\frac{1}{24,000}

Step-by-step explanation:

we know that

When we compare positive fractions with the same numerator, the largest rational number will be the fraction with the lowest denominator

In this problem we have

\frac{1}{24,000}  and   \frac{1}{3,168,000}

Both numerator are equal

Compare the denominators

24,000 < 3,168,000

therefore

\frac{1}{24,000}  is the largest rational number
