Real Number number that appears on the number line as either a rational number or an irrational
number
Rational Number any real number that can be written as a fraction, terminating decimal, or repeating
decimal
Irrational Number numbers that can be written as fractions, square roots, cube roots, and pi *not all
roots are irrational
Calculating Percents 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 Percent Increase = original value-new value/original value x 100
Percent Decrease = new value-original value/original value x 100
Fractions to Decimals divide numerator by denominator
Decimals to Fractions 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 convert fraction to decimal then multiply by 100
Percent to Fractions 1. remove %
2. write the number from step 1 in the numerator and write 100 as the denominator
3. simplify
Percent to Decimal divide by 100 or just move decimal to the left 2 places
Decimals to Percent multiply by 100 or just move the decimal to the right 2 places
Estimation/Approximate Values round the numbers so that there is only on nonzero digit in each number
Reconciliation of a Checking/Savings Account 1. add up all the deposits
2. add up all the checks
3. add the total deposits amount to the previous balance
