How do you rewrite the fractions to represent pieces that are the same size?

This is converting fractions into equivalent fractions, which is achieved by multiplying (or dividing) the numerator (top number) and denominator (bottom number) by the same number.

eg 2/6 → (2×2)/(6×2) = 4/12

eg 2/6 → (2×3)/(6×3) = 6/18

eg 2/6 → (2÷2)/(6÷2) = 1/3

Thus 2/6, 4/12, 6/18, 1/3 all represent the same value.
