Denominator 1 ≠ Denominator 2.

We need matching denominators

Multiply fraction 1 numerator * fraction 2 denominator.

Multiply fraction 2 numerator by the fraction 1 denominator

Fraction 1 - Fraction 2 = | Numerator 1 * Denominator 2 - Numerator 2 * Denominator 1 |

Denominator 1 * Denominator 2 |

Fraction 1 - Fraction 2 = | 4 * 3 - 1 * 5 |

5 * 3 |

Fraction 1 - Fraction 2 = | 12 - 5 |

15 |

Fraction 1 - Fraction 2 = | 7 |

15 |

Our fraction is already reduced.

This means our fraction has a Greatest Common Factor (GCF) = 1.

Therefore, we have our answer:

Answer = 7/15

Answer = | 7 |

a/c + b/c = (a + b)/c

a/c - b/c = (a - b)/c

a/c * b/c = ab/c * c

a/b/c/d = ad/bc

Reciprocal of a/b = b/a

For more math formulas, check out our Formula Dossier

a/c - b/c = (a - b)/c

a/c * b/c = ab/c * c

a/b/c/d = ad/bc

Reciprocal of a/b = b/a
