Using a fraction wall

How can we create a fraction that is equivalent to ½?
A fraction consists of a top number called the numerator and a bottom number called the denominator.
In the fraction ½, the denominator indicates that the whole is divided into 2 equal parts.
Equivalent fractions | Year 3 MathematicsBy looking at a fraction wall, you can see that 1/2 is equal to 2/4 and also equal to 3/6.
