How do you convert a fraction into a decimal? -CORRECTANSWER Divide the top
number (numerator) by the bottom number (denominator).
What is the key step that must be performed in order to add or subtract unlike fractions?
-CORRECTANSWER You must find the lowest (least) common denominator.
How do you divide on fraction by another? -CORRECTANSWER You invert the divisor
and multiply the numerators together and the denominators together.
How can you convert a decimal into a percent? -CORRECTANSWER (1) Multiply the
decimal by 100 and add the percent sign. (2) Move the decimal point two places to the
right and add the percent sign.
,How do you convert a fraction into a percent? -CORRECTANSWER Convert it to a
decimal, move the decimal point two places to the right and add the percent sign.
How do you change a decimal into the nearest equivalent fraction? -
CORRECTANSWER Multiply the decimal by the desired denominator. The result
becomes the numerator in the fraction.
How are two different ways that a ratio may be expressed? -CORRECTANSWER (1) As
a fraction. (2) By placing a colon (:) between the two numbers. (3) By using the word
"to" between the two numbers.

mass.
Matter may exist in what three states? -CORRECTANSWER Solid, liquid, gas.
Define kinetic energy. -CORRECTANSWER Kinetic energy is the energy of motion.
, Work is the product of what two factor? -CORRECTANSWER Force and the distance
moved.
What are the parts of a lever? -CORRECTANSWER A rigid bar and a pivot point called
the fulcrum.
A wheelbarrow is an example of what class of lever? -CORRECTANSWER A second-
class lever.
Are all three states of matter affected by thermal expansion and if so, which state is
affected most? -CORRECTANSWER All three states are affected, with gas being
affected the most.
What is a British Thermal Unit? -CORRECTANSWER The amount of heat energy
required to change the temperature of 1 pound of water 1 degree Fahrenheit.
