4x^2y^26
=(2^2)(x^2)(y^7*2+4*3)
=(4)(x^2)(y^14+12)
=4x^2y^26
Each gray square: 2x2=4 tiles. 6 gray squares: 6x4=24 tiles.
Total number of tiles: 12x10 = 120, 24 of those are gray.
So 120-24 = 96 are white.
96-24 = 72 more white than gray
Just try different ways to find a common denominator, add from there and then simplify.
