Question: A snake's head is one-tenth its length. If a snake is 10 feet long, calculate the length of the rest of its body minus the head.
Answer with step-by-step thinking: A snake's head is one - tenth its length, which is 1 / 10 * 10 = 1 foot. Since the snake's head is 1 foot, the rest of its body is 10 - 1 = 9 feet long.
So the answer is 9.
