3. What is the meaning of 4.32 X 10-2 ?
a. 0.00432
b. 432
c. 0.432
d. 0.032
This will be a small number due to the negative exponent, so we will move the decimal to
the left to show that the number is less than one. We will move it two spaces because the
exponent is -2. Moving the decimal of 4.32 two places to the left will give 0.0432. In double
checking this answer, we would need to move the decimal two places to the right to yield
4.32 x 10-2 so this answer makes sense.

5. Arrange the following values from smallest (top) to largest (bottom)
a. 10-5
b. 101
c. 1
d. 106
e. 10-2
f. 104
g. 10-3
10-5 is the smallest, and moving to largest with 10-3, 10-2, 1, 101, 104, and the largest at 106.
6. Select the appropriate value for each part of the equation.
12 inches will go on top, and 1 foot will go on the bottom. These two values are equal, so we
can write them as a fraction.
7. Is the measurement quantitative or qualitative?
Quantitative --- That shirt is orange, That object is beautiful, The patient’s pain level is 5
Qualitative --- The patient weighs 150 lbs, The patient’s fever is 38.1 C
Patient weight and temperature are both quantitative measurements, while pain level,
color, and qualities (beautiful) are qualitative measurements.
8. Determine if the measurement is metric or English.
Metric --- The patient is 130 centimeters tall, Walk 500 meters, Add 25 g of salt,
English --- The patient weighs 150 pounds, Walk 500 miles, Add one cup of sugar to the
solution
Centimeters, grams, and meters are all metric measurements, while pounds, cups, and
miles are English measurements.
9. Match the unit to the measurements.
Length --- Feet, Meters
Volume ---Liters, Cups
Weight/Mass ---Pounds, Grams
Meters and feet both measure length, liters and cups measure volume, and pounds and
grams measure weight or mass.
