Question

Write the ratio as a fraction in lowest terms. 16 hours to 2 days. Compare in hours.

Answer 1

To compare the hours, both terms must be measured in hours. Right now one is in days.

To convert days to hours simply multiply by 24.

2 × 24 = 48.

This means that the unreduced ratio is 16 : 48. As a fraction, this is 16 / 48.

To reduce this fraction, find the GCD (greatest common divisor) of 16 and 48. The GCD is the largest whole number that fits into both terms of the fraction without any remainders e.g. for 14 and 7, the GCD is 7 since both 14 and 7 are divisible by seven.

Once you've found the GCD of 16 and 48, simply divide both numbers by the GCD, and the fraction will be in lowest terms.
