All fractions must have the same (common) denominator (LCD). once this is
accomplished then add or subtract the numerator
ex. 1\/4 + 5\/6 LCD = 12
12 divided by 4 = 3×1 = 3\/12
12 divided by 6 = 2×5 = 10\/12
3\/12 + 10\/12 = 13\/12 = 1 1\/12
adding\/subtracting fractions
Represents part of a whole (or more than) a whole number. to do so, decimals use
place values to the right of the decimal point.
ex. 78.24693
decimals
All numbers on the number line.
real numbers
Numbers that can be written as fractions.
rational numbers
1, 2, 3, 4, etc.
whole & counting (natural) numbers
Any number that can be written in % form. A (numerator) and B (denominator) equals
intergers
ex. 3\/4, 5\/7, 4\/5
B is never 0
fractions
5 = 5\/1
whole number to fraction
3\/4, 1\/2
proper fraction
9\/5, 12\/12
improper fraction
one = tenth
two= hundreth
three= thousandth
four= hundred thousands
five= hundreth thoudandths
six= millionth
ex. 0.78 = seventy eight thousandths
2.305 = two and three hundred five thousands
place values
the sum of a whole number and a fraction OR just another way of writing an improper
fraction.
ex. 1 4\/5 really means 1 + 4\/5
mixed number
a fraction (a\/b) where a = 1
ex. 1\/2
unit fraction
a fraction (a\/b) where a & b are both fractions
ex. 1\/2\/1\/2
complex fraction
equal fractions
ex. 1\/5, 10\/50, 100\/500
equivalent fractions
9\/5 = 1 4\/5
converting improper fractions to a mixed number
1 4\/5 = 9\/5
converting mixed number to an improper fraction
multiply the numerator and denominator (no need to change denominator to match)
ex. 4\/5 x 2\/3 = 8\/15<\/p>\n","protected":false},"excerpt":{"rendered":"
