How to work out the percentage of an amount
Using bar models
Have you used a bar model in maths before?
A bar model can help you picture maths concepts and solve problems.
The two bars represent two amounts.
In the activity below the top green bar shows the weight in grams and the bottom purple bar shows the percentage of the amount as a decimal.
Dragging the orange handle on the purple bar to the 0.50 marker will automatically move the green bar above it to reveal the weight.
Drag the orange handle to change the percentage.
