percentage ruler (mixture)
Use a slider to mix the apples and mangos or undo the mixing. Learners may guess the percentages before or after the mixing.
When the items are arranged in a line, the percentage ruler can be used to visualise the percentages by adjusting the 100% mark.
Click the apples or mangos sliders and use the style bar to hide the labels (which include the numbers) if needed.
You may use the following calculator to show and record your calculation.
