1. A ___________ describes the number of equal parts of a whole.
In a fraction, the number above the ________ ______ is called
the ___________, and the number below is called the

called an __________ __________.

2. Two fractions are __________ if they represent the same number.
____________ ___________ represent the same portion of a whole.
A fraction is in _________ _______ , or _______ _____ , when the
numerator and denominator have no common factors other than 1.
_________ fractions are simplified and built up just like numerical
fractions.

3. To __________________ , multiply the numerators and multiply the
denominators. Simplify the result, if possible.
When a ______________________________, it indicates that we are
to find a part of some quantity using multiplication.
One number is the ___________ of another if their product is 1.
To find the ___________ of a fraction, _______ the numerator and
denominator.

4. • Simplify each fraction, if possible.

5. • Multiply and Simplify.

6. • Exponential Expressions

8. Solve:

9. To _______________ to a certain decimal place value, locate the
rounding digit in that place.
Look at the ________ directly to the right of the rounding digit.
If the test digit is __________ , round up. If it is 4 or less, round down
by keeping the rounding digit and dropping all the digits to its right.

10. Round 3,706.0815 to the nearest thousandth.
Round -0.0614 to the nearest tenth.
Round 11.314964 to the nearest ten-thousandth.

11. Add: 15.82 + 19 + 32.995.
Write the problem in vertical form and add, column by
column, working right to left.
Subtract: 8.4 – 3.029.

12. Use the same rules that are used for adding and
subtracting integers.
Add: -21.35 + (-64.52).
Subtract: -8.62 - (-1.4).

13. Line up the numbers and multiply like whole numbers.
Move the decimal point in the product the number of
decimal places in both factors.

14. Line up the numbers and multiply like whole numbers
and follow the rules for multiplying signed integers.
Move the decimal point in the product the number of
decimal places in both factors.

15. The base of an exponential expression can be a
positive or negative decimal.

16. To divide with a decimal divisor:
1. Write the problem in long
division form.
2. Move the decimal point of
the divisor so that it becomes
a whole number.
3. Move the decimal point of
the dividend the same
number of places to the right.
4. Write a decimal point in the
quotient directly above the
decimal point in the dividend.

17. Use the rules for dividing integers.

18. Use the rules for ________________ to evaluate
expressions and formulas.

19. To write a fraction as a decimal, _______ the
numerator of the fraction by its denominator.

20. If the division process never gives a remainder of zero
(____________), we call the resulting decimal a
____________ decimal.

21. To write a mixed number in decimal form, we need
only find the decimal equivalent for the fractional part
of the mixed number.

22. Write the fraction in its __________ decimal form.

23. To evaluate expressions that can contain both fractions
and decimals, we can work in terms of decimals or in
terms of fractions.
