Express each ratio as a fraction in its lowest terms

18hours to 2days

18 hr : 48 hr

18 / 48 = 3 / 8

To express the ratio of 18 hours to 2 days as a fraction in its lowest terms, we need to convert both the hours and the days to a common unit. Let's convert both 18 hours and 2 days to hours.

Since there are 24 hours in a day, we can multiply 2 days by 24 to convert it into hours:
2 days × 24 hours/day = 48 hours

So, the ratio of 18 hours to 2 days can be expressed as 18:48.

To reduce this ratio to its lowest terms, we can divide both the numerator and denominator by their greatest common divisor (GCD). In this case, the GCD of 18 and 48 is 6.

Dividing both 18 and 48 by 6, we get:
18 ÷ 6 = 3
48 ÷ 6 = 8

So, the reduced fraction is 3:8, which represents the ratio of 18 hours to 2 days in its lowest terms.
