Improper Fraction - ANSWER//fraction whose numerator is larger than its denominator
Proper Fraction - ANSWER//fraction whose numerator is less than its denominator
Least Common Denominator (LCD) - ANSWER//smallest common multiple of the
denominators; the least number that both denominators divide into evenly
Simplified Fraction - ANSWER//fraction in its simplest form
Steps for Multiplying decimals - ANSWER//1. Set up numbers as if they were whole
numbers
2. multiply the numbers
3. count the number of decimal places in the factors
4. start from the right and move the decimal the number of decimal places you counted
in step 3
5. place the decimal
, Steps for Dividing Decimals - ANSWER//1. set up the problem to be an equivalent in
which the divisor is a whole number by moving the decimal in the dividend the same
number of places that you moved the decimal in the divisor
2. when doing long division place the decimal in the quotient directly above the decimal
point in the dividend
3. divide as if it were a whole number
Real Number - ANSWER//number that appears on the number line as either a rational
number or an irrational number
Rational Number - ANSWER//any real number that can be written as a fraction,
terminating decimal, or repeating decimal
Irrational Number - ANSWER//numbers that can be written as fractions, square roots,
cube roots, and pi *not all roots are irrational
Calculating Percents - ANSWER//1. change written statement into a math equation
2. solve for the unknown quantity
3. rewrite the statement and makes sure that the answer is reasonable
Percent increase/decrease - ANSWER//Percent Increase = original value-new
value/original value x 100
Percent Decrease = new value-original value/original value x 100
Fractions to Decimals - ANSWER//divide numerator by denominator
Decimals to Fractions - ANSWER//1. write the digits of the decimal number in the
numerator of the fraction
2. write a number that is the power of 10 as the denominator, the number should have
as many zeroes as there are decimal places to the right of the decimal
3. write the decimal fraction in simplest form
Fraction to Percent - ANSWER//convert fraction to decimal then multiply by 100
Percent to Fractions - ANSWER//1. remove %
2. write the number from step 1 in the numerator and write 100 as the denominator
3. simplify
Percent to Decimal - ANSWER//divide by 100 or just move decimal to the left 2 places
Decimals to Percent - ANSWER//multiply by 100 or just move the decimal to the right 2
places
Estimation/Approximate Values - ANSWER//round the numbers so that there is only on
nonzero digit in each number
