Express each ratio as fraction in it's lowest term.
18hours:2days
18hr : 2day = 18hr : 48hr = 18:48 = 3:8
To express the ratio 18 hours to 2 days as a fraction in its lowest terms, we need to convert the hours and days to a common unit. Since there are 24 hours in one day, we can convert hours to days by dividing by 24.
First, let's convert 18 hours to days:
18 hours ÷ 24 = 0.75 days
Now, the ratio becomes:
0.75 days : 2 days
To express this ratio as a fraction, we can write:
0.75/2
However, we need to simplify this fraction to its lowest terms. To do this, we find the greatest common divisor (GCD) of the numerator and denominator, and divide both the numerator and denominator by it.
The numerator (0.75) and denominator (2) don't have any common factors other than 1, so we can't simplify this fraction further. Therefore, the ratio 18 hours to 2 days expressed as a fraction in its lowest terms is:
0.75/2
