Practise Share of total

What you will practise

Divide the part by the matching whole. Unit share and revenue share use different numerators and denominators.

part / SUM(total_range)

The syntax above is a guide. Read the data and each task to choose the right arguments for your formula.

    Calculate item A's share of all ordered units using B2:B4.

  2. Exercise 2 · answer in E10

    Calculate item B's share of total sales value using quantity times price.

  3. Exercise 3 · answer in E10

    Calculate the combined share of units for the first two items.

Before you check your answer

  • Keep the source data intact. Write your answer in the highlighted result cell. Changing a source value changes the question instead of solving it.
  • Use the requested cells. Check the first and last row of a range and read its column heading. A plausible total can still come from the wrong data.
  • Reference values that can change. A fixed number may match today's sheet. A cell reference keeps the formula connected when the source values change.

How the answer is checked

The workbook evaluates your formula against the requested result. It also checks the skill being practised and tests the formula with changed source data, so a fixed answer that happens to match is not enough.

Use progressive hints when you need help, then try the task again with fresh data. Correctly solving a step opens the next exercise.
