The top strip is given. Build the bottom one: set the number of saw-cuts with denominator −/+ and the colored pieces with numerator −/+ (or drag: right = more colored pieces, up = more cuts), so it is the same SIZE as the top strip but with a different number of pieces. The balance levels when the two fractions are equal. Then press Check
