Add the following, using the lowest common denominator:

2/3+1/6 = 1/2+1/8 = 2/3+1/4 = 1/3+5/12+1/6=
1/10+1/4+3/5= 1/6+2/3+2/9=

Subtract the following: 2/3-1/3= 6/7-3/7= 11/15-7/15
Subtract the following using the lowest common denominator: 3/4-1/2= 7/9-1/3= 5/6-1/4=
Multiply the following fractions, reducing to lowest terms

1/2x3/5= 3/4x1/5= 2/5x2/3= 2/3x1/2= 7/8x4/5 4/9x9/10=

Find the lowest number that the two denominators are multiples of. Multiply the numerator and denominator for the fractions by a number that will get the denominator to be that lowest common multiple. Then, add or subtract. This works for addition and subtraction. (Example: 1/4 + 2/3 = 3/12 + 8/12 = 11/12)

Multiplying: Just multiply the numerators. Then multiply the denominators. Then divide the first answer by the second answer. (Example: 3/4 X 2/3 = 6/12 = 1/2)

Dividing: Same as multiplying, except switch the second fraction, then multiply. (Example: 3/4 / 2/3 = 3/4 X 3/2 = 9/8)

Fraction to Decimal: Turn the denominator into 100 by multiplying by a certain number and divide the numerator (after the numerator is multiplied by that certain number) by 100. (Example: 3/5 X 20/20 = 60/100 = 60 / 100 = .60)

Decimal to Fraction: Multiply decimal by 100. Then divide answer by 100. (Example: .23 X 100 = 23 = 23/100)

Fraction to Percent: Turn the denominator into 100, also multiply the certain number for the numerator, then take the numerator and put it next to the percent sign. (Example: 1/4 = 25/100 = 25%)
