To convert 3/4 of an hour to a decimal, you can divide the fraction by the total number of minutes in an hour (60 minutes). This will give you the equivalent decimal value.

First, you can convert 3/4 of an hour to minutes by multiplying by 60: 3/4 hour x 60 minutes/hour = 45 minutes
Now that you have 45 minutes, you can divide by 60 to convert to a decimal: 45 minutes ÷ 60 minutes/hour = 0.75
Therefore, 3/4 of an hour is equal to 0.75 in decimal form.
Another way to think about this is to recognize that 3/4 can also be written as 0.75 in fraction form. This is because 0.75 represents 75% of the total hour, and 75% is equivalent to 3/4 when expressed as a fraction.
Decimal values are often used in calculations and measurements because they can be easily added, subtracted, multiplied, and divided. Converting fractions to decimals allows for easier manipulation of values in mathematical operations.
In conclusion, 3/4 of an hour is equal to 0.75 in decimal form, which can be found by dividing 3/4 by 60 to get the equivalent value in hours and minutes.
