Worksheet Overview

In this worksheet you have to work out different possibilities to make the given sum correct by filling in the gaps with suitable number pairs.

 

Example

Find 10 different ways of making this sum correct.

 

370 + ___ + ___ = 500

 

Answer

We need to find pairs of numbers which add to 500 - 370 = 130

For example 60 + 70, which is shown in the first answer below. There are many other possibilities, some of which are shown below.

 

  1. 370 + 60 + 70 = 500
  2. 370 + 70 + 60 = 500
  3. 370 + 41 + 89 = 500
  4. 370 + 30 + 100 = 500
  5. 370 + 93 + 37 = 500
  6. 370 + 82 + 48 = 500
  7. 370 + 15 + 115 = 500
  8. 370 + 21 + 109 = 500
  9. 370 + 44 + 86 = 500
  10. 370 + 74 + 56 = 500
