Percentage of a Quantity

Percentage of a Quantity in NSW Year 8 maths (NESA outcome MA4‑FRC‑C‑01) uses a decimal multiplier: divide the percentage by 100, then multiply, so 62% of 250 is \(0.62 \times 250 = 155\).

You will find percentages above 100% and below 1%, change units, add 10% GST to a price, apply two percentages one after the other, work out a real estate agent’s commission and round money to the nearest cent. You will also compare a percentage discount with a dollar discount and decide which pack of mince is better value. It is part of Year 8 Fractions and Percentages.
