What fraction of a clockwise revolution does the hour hand of a clock ...
Understanding Clock Revolutions
When analyzing the movement of the hour hand on a clock, it is essential to know that a full clockwise revolution is equivalent to 12 hours. The clock can be divided into 12 equal sections, with each hour representing 1/12 of a full revolution.
Calculating the Fraction of Revolution
To find the fraction of the revolution for each time interval, you can determine the number of hour sections between the starting and ending point, then divide that by 12.
a) From 3 to 9
- Movement: 9 - 3 = 6 hours
- Fraction: 6/12 = 1/2
b) From 4 to 7
- Movement: 7 - 4 = 3 hours
- Fraction: 3/12 = 1/4
c) From 7 to 10
- Movement: 10 - 7 = 3 hours
- Fraction: 3/12 = 1/4
d) From 12 to 9
- Movement: 9 - 12 = 9 hours (or -3 hours in a clockwise direction)
- Fraction: 9/12 = 3/4
e) From 1 to 10
- Movement: 10 - 1 = 9 hours
- Fraction: 9/12 = 3/4
f) From 6 to 3
- Movement: 3 - 6 = -3 hours (or going back 3 hours clockwise)
- Fraction: 9/12 = 3/4
Summary of Fractions
- From 3 to 9: 1/2
- From 4 to 7: 1/4
- From 7 to 10: 1/4
- From 12 to 9: 3/4
- From 1 to 10: 3/4
- From 6 to 3: 3/4
This systematic approach allows for a clear understanding of the hour hand's movement around the clock face.
