Place values are used to order whole numbers.

Which of the following four sportspeople earns more in a week?

- Player A - £310,500
- Player B - £309,500
- Player C - £295,500
- Player D - £315,500

First, put each sportsperson’s salary into a place value table.

Hundred thousands | Ten thousands | Thousands | Hundreds | Tens | Units | |
---|---|---|---|---|---|---|

Player A | 3 | 1 | 0 | 5 | 0 | 0 |

Player B | 3 | 0 | 9 | 5 | 0 | 0 |

Player C | 2 | 9 | 5 | 5 | 0 | 0 |

Player D | 3 | 1 | 5 | 5 | 0 | 0 |

Next, look at each column in turn from the left:

- the smallest digit in the hundred thousands column is 2, so Player C earns the lowest amount
- the smallest digit in the ten thousands column is 0, so Player B earns less than Players A and D
- the smallest digit in the thousands column is 0, so Player A earns less than Player D

From highest to lowest, the order is:

- Player D - £315,500
- Player A - £310,500
- Player B - £309,500
- Player C - £295,500

Inequality symbols can be used to compare the size of numbers.

Symbol | Definition |
---|---|

> | Greater than - the wider part of the inequality sign faces the larger number. |

< | Less than - the wider part of the inequality sign faces the larger number. |

≥ | Greater than or equal to - the wider part of the inequality sign faces the larger number. |

≤ | Less than or equal to - the wider part of the inequality sign faces the larger number. |

means 4,000 is greater than 3,900.

means 3,900 is less than 4,000.
