Percentages (Medium)

Don't forget, per cent means per hundred, e.g. 10% = 10100. Suppose you were asked to find 10% of 50, how would you do it? This is how you would do it: 10100 × 50 = (10 × 50) ÷ 100 = 5. It's as simple as that!

There are various ways to write numbers such as decimals, fractions or percentages. If I picked a bunch of flowers from the garden with 9 purple flowers and 3 yellow, what percentage of yellow flowers do I have? 3 out of 12 is one-quarter which can be written as either 0.25, 14 or 25%.

This is the first of two 11-plus Maths quizzes on percentages. In this quiz you'll get some practice in working out percentages with various numbers. Make sure you play this one first before moving onto the difficult quiz.
