Interactive Ratio Part of an Amount

This Excel based ratio activity has a value given for part of an amount and a given ratio using diagrams to visually show students the parts of a ratio from part given information. The ratio can be set manually using scroll bars and then amounts are randomly calculated based on ratios selected. Amounts of each part can be shown on diagrams by selecting buttons or clicking onto coloured sections of diagrams. You will need to enable macros on opening. Enjoy :)
