Understanding Fractions and Ratios

Fractions: The Basics

A fraction has a numerator (top number) and a denominator (bottom number). It shows how many parts of a whole you have. If you can picture it, like a cake cut into slices, it becomes easier.

Ratios: Comparing Parts

Ratios tell us how much of one thing there is compared to another. If you have 3 apples and 2 oranges, the ratio is 3:2. Imagine lining these fruits up — it helps to see the comparison.

Quick check

1. What is 1/4 of 12?
2. If there are 5 boys and 3 girls, what is the ratio of boys to girls?
3. Simplify the fraction 8/12.

(Answers: 3, 5:3, 2/3)

Common mistakes students make

1. Skipping Steps: Many students jump straight to the answer without showing their working. This can lead to careless mistakes.

   • Fix it: Write down each step clearly. It helps you track your thought process.

2. Misreading Questions: Sometimes, the pressure makes us read too fast.

   • Fix it: Slow down, read the question twice. Highlight key details.

3. Mixing Up Numerators and Denominators: It’s easy to confuse which number goes where.

   • Fix it: Remember, the numerator is the part you have, the denominator is the whole.

Exam tip

Focus on presentation and timing. Always show your workings, even if you think they’re not needed. It helps you get partial marks. Time yourself during practice sessions to get familiar with the pace of the exam.

Worked example 1: Fraction of a Whole

Question: What is 3/5 of 20?

Solution:

Step 1: Identify the whole number. Here, it’s 20.

Why: Knowing the whole helps you find the part.

Step 2: Multiply the whole by the fraction: $20 \times \frac{3}{5}$.

Why: Multiplying gives you the part of the whole.

Step 3: Simplify the multiplication: $20 \times \frac{3}{5} = 12$.

Why: Simplifying shows you the answer — 12 is 3/5 of 20.

Worked example 2: Working with Ratios

Question: In a class of 30 students, the ratio of boys to girls is 2:3. How many boys are there?

Solution:

Step 1: Add the parts of the ratio: 2 + 3 = 5 parts.

Why: Total parts help you divide the whole evenly.

Step 2: Divide the total students by the total parts: $30 \div 5 = 6$.

Why: This tells you how many students each part represents.

Step 3: Multiply the number of parts for boys by the students per part: $2 \times 6 = 12$.

Why: This gives you the number of boys — 12 boys in the class.

Quick summary

• Fractions are parts of a whole; ratios compare parts.
• Show your workings for partial marks.
• Read questions twice to avoid mistakes.
• Use simple steps to solve problems without panic.
• Practise timing to manage exam stress.
