Description
Who it’s for: anyone who knows the ideas, for example from the Ratios and proportion season, and wants the calculations to become second nature, or to check their figures before a meeting.
What’s inside: 5 self-marking practice tools, with an end-of-season quiz and a self-marking Excel workbook.
- A ratio in its simplest form
- Each share of an amount shared in a ratio
- The unit rate (price per kg)
- The new quantity for a scaled order
- An amount in rand from a foreign currency
How it works: pick a tool, choose your industry and currency, work out the answer and check it. Press New numbers and go again, as often as you like; the working shows when you get it wrong.
