A uniformly growing and uniform grassland is divided into two unequal parts, A and B. A group of cows first grazes on grassland A, finishing it entirely in exactly 7 days. They then continue grazing at the same rate on grassland B, finishing it in 4 days. At this point, grassland A has completely regrown to its original state as it was when the cows initially started grazing. What is the simplest integer ratio of the area of grassland A to the area of grassland B?
