Mass Fraction: The Link to Percentages
Juice labels say "10% fruit juice" — that is also a fraction of a whole, just expressed through percentages.
A part of the whole on labels
"Sugar content 5%" means: for every 100 parts of the product, 5 parts are sugar. This is the same percentage idea applied to a product's makeup.
💡 Anchor: look at product labels at home together — composition percentages show up everywhere.
Practice
A 100 ml juice box contains 20% fruit juice. How much is that in milliliters? 100×0.2=20 ml.
