## Task 2 - 200712

From an ancient Egyptian arithmetic book (1700 BC) comes the following problem:

A traveler notices that a shepherd is leading 70 sheep to pasture. He asks the shepherd: "Are the sheep you are leading here all of your sheep?"

"No," the shepherd replies, "I am only leading two-thirds of a third of the entire herd entrusted to me to pasture."

Determine the total number of sheep in the entire herd entrusted to this shepherd!
