We have two paint mixers to enable you compare two different mixtures visually.

- In Mixture A, use 3 cups of green and 2 cups of white paint. The Tape Diagram is displayed below.
- Check the
**Percent**box, check the**Green**and**White**boxes to see the percentage composition of the mixture. - Uncheck the boxes.
- Now check the

- Check the
**Percent**box, check the**Green**and**White**boxes to see the percentage composition of the mixture. - Uncheck the boxes.
- Now check the
**Fraction**box, check**Green**and**White**boxes to see the fraction of each paint in the mixture. - Now visually compare the colors of the paint in the two containers.
