Today for maths we were talking about Fractions and mixed numerals.To convert fractions in different forms you need to make your fraction the exact same size and to see if you did that you need to put your fraction on top of the other to see if they were the same size. Fractions can be represented in different ways by the size,numerator,and the denominator.
