- Most space shuttles orbit the earth once every hour. How many orbits are made every 24 hours?
PART II: PRACTICAL APPLICATION
Directions: Arrange sockets and drill bits in fractional sizes from smallest to largest.
Background In the United States, tools are typically classified using either English or metric units. For example, socket sets are sold in fractional sizes (fractions of an inch), or metric sizes (millimeters). When fractional sizes are used, it is important to be able to compare the relative size of each tool by comparing the fractions.
Below are the 3 different sets.
SET A: SOCKETS
3/8
13/16
9/32
5/8
3/16
1/4
11/16
3/4
15/16
9/16
1/2
11/32
7/32
5/16
7/8
7/16
SET B: SMALL DRILL BITS
15/64
5/32
1/4
5/64
3/32
3/16
7/32
13/64
1/8
7/64
9/64
1/16
11/64
SET C: BIGGER DRILL BITS
13/32
23/64
7/16
1/4
9/32
19/64
5/16
17/64
3/8
29/64
1/2
25/64
11/32
21/64
27/64
15/32
31/64
Develop a plan for ordering the different sets and describe it below.
Order Set A: Sockets.
Order Set B: Small Drill Bits
Order Set C: Bigger Drill Bits
Think about your everyday life. Do you make any measurements or need to order fractions? Do you find some fractions easier to work with, such as commonly seen ones like 1/2, 1/4, or 2/5?
PART III: JOURNAL ACTIVITY
Directions: Write a page about why it is necessary to have a common denominator before adding or subtracting fractions. Also, note pros and cons of using mixed numbers.
