This is a simple question on converting time to decimal form. Firstly, we need to understand how to express time in hours and minutes. Time is typically measured in hours and minutes. One hour is a whole, while minutes represent a fraction of an hour. A decimal is a way to represent numbers that are not whole, using a decimal point (.) to separate the whole part from the fractional part. The numbers to the left of the decimal point represent the whole hours, and those to the right represent the fractional part of an hour.
1 hour and 40 minutes in decimal form is written as 1.67.
To convert 1 hour and 40 minutes to a decimal, we will first convert the minutes to a fraction of an hour. Since there are 60 minutes in an hour, 40 minutes is 40/60 of an hour.
Step 1: Identify the whole hours and the minutes. Here, the whole part is 1 hour, and the minutes are 40.
Step 2: Convert the minutes to a fraction of an hour: 40 minutes is 40/60 = 2/3 of an hour.
Step 3: Convert the fraction to a decimal: 2/3 is approximately 0.67 when converted to a decimal.
Step 4: Add the decimal to the whole part: 1 (whole hour) + 0.67 (fractional hour) = 1.67.
Therefore, 1 hour and 40 minutes as a decimal is 1.67.
