It's a simple question on converting time to decimal format. First, we need to understand how time is structured and how decimals work. Time is traditionally measured in hours and minutes. There are 60 minutes in an hour. A decimal represents a part of a whole, using a decimal point (.) to separate the whole number from the fractional part. The numbers to the left of the decimal point represent the whole, and those to the right represent the fractional part.
Answer 42 minutes as a decimal of an hour can be written as 0.7. Explanation To express 42 minutes as a decimal of an hour, we divide the number of minutes by the total number of minutes in an hour. Let's break down the process step by step: Step 1: Identify the total minutes in an hour (60 minutes) and the given minutes (42 minutes). Step 2: Divide the given minutes by the total minutes in an hour: \( \frac{42}{60} \). Step 3: Simplify the fraction if possible. Here, \( \frac{42}{60} = \frac{7}{10} \). Step 4: Convert the simplified fraction to a decimal. \( \frac{7}{10} = 0.7 \). The answer for 42 minutes as a decimal of an hour is 0.7.
Minute: A unit of time equal to one-sixtieth of an hour. Hour: A unit of time equal to 60 minutes. Decimal: A number expressed in the scale of tens, using a decimal point to separate the whole number from the fractional part. Fraction: A numerical representation indicating a part of a whole, consisting of a numerator and a denominator. Simplification: The process of reducing a fraction to its simplest form.
