### Chapter 1

Solving: | Steps: |
---|---|

Addition of Fractions | Same denominator fractions Add numerators and write sum over denominator. When adding fractions with different denominator: Make the denominator the same by finding LCD. Then whatever you do to the top do to the bottom. Add, then simplify fraction. |

Subtraction of Fractions | Same denominator fractions subtract numerators, write sum over denominator.Subtracting different denominator fractions: find LCD what is done to the numerator is done to the denominator.Subtract numerators, denominators stay the same. Simplify if needed. |

Multiplication of Fractions | Fractions with no mixed numbers: multiply across NxN, DxD then simplify to lowest terms. Mixed number fractions: change mixed numbers into improper fractions. Whole number x denominator+original numerator = [?] /denominator. Then multiply NxN/DxD=fraction |

Division of Fractions | Dividing fractions, inverse the second fraction and multiply. Write as an improper fraction then reduce to lowest form. |

Fractions to Decimals | Numerator - Denominator = Decimal |

Reading Decimals | 0.2 is read as two tenths (2/10) , 0.02 is read as two hundredths (2/100) 0.002 is read as two thousandths (2/1000) |

Rounding of Decimals | Round off the decimal and drop the final number. Ex: 4.624 becomes 4.62 * Exception: if the final number is 5 or more, drop it and then increase the adjacent number by 1. Ex: 2.36 becomes 2.4. |
