In KS3 Maths you'll be asked to work on algebra. One aspect of algebra is equations. These can be quite daunting at first - especially when they involve fractions. But don't worry. This quiz should help you get your head around fractional equations.
Do you remember working on fractions? If so, you'll know all about numerators (the numbers above the line in fractions) and denominators (the numbers below the line). So, you won't be surprised to hear that numerators and denominators also appear in fractional equations. It's all quite simple once you learn the rules. Keep practising and fractional equations will soon be second nature to you.
The first few questions in this quiz will act as revision on what fractions are all about - then we get into the more interesting stuff! Flex your brain muscles and see if you can get full marks. But don't rush. Take your time and read each question carefully before submitting your answers.
