🛎️ What is a Fraction?
- A fraction shows part of a whole.
- For example, if a pizza is cut into 8 equal slices and you take 3, the fraction is 3/8.
🛎️ Parts of a Fraction (Example: 3/8)
- The numerator (3) shows how many parts are taken.
- The denominator (8) shows how many equal parts the whole is split into.
🛎️ Exam Rule: Equal Parts
- Fractions only work when the whole is divided into equal parts.
- If the parts are not equal, you cannot write a correct fraction.
🛎️ How Do You Find a Fraction of an Amount?
- Divide the total by the denominator to find one part: 20 ÷ 4 = 5.
- Multiply that by the numerator to get the answer: 5 × 3 = 15.
- So, 3/4 of 20 = 15.
🛎️ Finding Missing Fractions
- The parts of a whole must add up to 1.
- To find a missing fraction, subtract the known fractions from 1.
