# My uncle Isacc and his cows

Level pending

My uncle Isaac has a big field divided into three areas of equal size. In the first area, my uncle has $$70$$ cows, and he told me, "these cows will eat all this grass in only $$24$$ days". In the second area, my uncle put $$30$$ cows, and he said, "they'll eat all the grass in $$60$$ days". In the third field, my uncle wants the grass to last for $$96$$ days. How many cows does he need?
