To make fractions easier for your Year 7 math exam, follow these simple steps:

1. Write Down the Fraction: First, write the fraction you want to work with. For example, let’s use $\frac{12}{16}$.

2. Find the GCD:

   • Next, find the greatest common divisor (GCD). This is the biggest number that can divide both the top number (numerator) and the bottom number (denominator).
   • For the number 12, the factors are: 1, 2, 3, 4, 6, and 12.
   • For the number 16, the factors are: 1, 2, 4, 8, and 16.
   • The GCD of 12 and 16 is 4.

3. Divide by the GCD:

   • Now, take the fraction and divide both the top and bottom by the GCD you found.
   • So for $\frac{12}{16}$, you divide both by 4:
     • Top: $12 \div 4 = 3$
     • Bottom: $16 \div 4 = 4$
   • This gives you $\frac{3}{4}$.

So, $\frac{12}{16}$ becomes $\frac{3}{4}$.
