Questions of this type ask you to enter your answer either as a
number in a single answer box or as a fraction in two separate
boxes — one for the numerator and one for the denominator — using
the computer mouse and keyboard.
Directions
For a single answer box, type a number in the answer box using
the keyboard.
- First, click on the answer box — a cursor will appear in the
box — and then type a number.
- To erase a number, use the Backspace key.
- For a negative sign, type a hyphen. For a decimal point,
type a period.
- To remove a negative sign, type the hyphen again and it will
disappear; the number will remain.
- Round your answer if a question so indicates; otherwise,
enter the exact answer. For a fraction, type the numerator and
the denominator in their respective boxes.
- For a negative sign, type a hyphen. A decimal point cannot
be used in a fraction.
- Fractions do not need to be reduced to lowest terms.
Sample Questions
1. The total amount of Judy’s water bill for the last quarter
of the year was $40.50. The bill consisted of
a fixed charge of $13.50, plus a charge of $0.0075 per gallon for
the water used in the quarter. For
how many gallons of water was Judy charged for the quarter?

3. Of the 20 lightbulbs in a box, 2 are
defective. An inspector will select 2 lightbulbs simultaneously
and at random from the box. What is the probability that neither
of the lightbulbs selected will be one that is defective?
Give your answer as a fraction.
Click on each box and type in a number.

Strategies
- Make sure you answer the question that is asked. Since there
are no answer choices to guide you, read the question carefully
and make sure to provide the type of answer required. Sometimes
there will be labels before or after the answer box to indicate
the appropriate type of answer. Pay special attention to units
such as feet or miles, to orders of magnitude such as millions
or billions, and to percents as compared to decimals.
- If you are asked to round your answer, make sure to round to
the required degree of accuracy. For example, if an answer of
46.7 is to be rounded to the nearest integer, you need to enter
the number 47. If no rounding instructions are given, enter the
exact answer. If your solution strategy involves intermediate
computations, you should carry out all computations exactly and
round only your final answer in order to get the required degree
of accuracy.
- Check your answer and make sure it is reasonable with
respect to the information given. You may want to use estimation
or another solution path to double-check your answer.
