CCSS Math Standard: 4.NF.3.b

Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model. Examples: 3/8 = 1/8 + 1/8 + 1/8 ; 3/8 = 1/8 + 2/8 ; 2 1/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8.

What if we took a fraction apart, then took those pieces apart, then recombined them, and then recombined those, arriving back to the original fraction?

You only have six digits to form three fractions. Can you combine them to get to 0?
