The creepy, crawly centipede has 100 legs.... so I've been told, but have never counted. (Although the name centipede means 'hundred- legged, the average is actually about 35 pairs of legs...'" (Encyclopedia.com, http://www.encyclopedia.com/articles/02481.html ). "Centi" means 100. There are 100 centimeters in every meter. 1 meter = 100 centimeters Let's look at 25 centimeters. We are going to rephrase your question: 1 meter stick is ___ times as long as 25 centimeters There are four "groups" of 25 in 100 (25, 50, 75, 100). This comes from the fact that 100 / 25 = 4 So 1 meter stick is _4_ times as long as 25 centimeters You can check this answer by seeing if 4 * 25 = 100 Yes, this is true. Try to apply this reasoning to your question. You can check your answer by seeing whether the product of your answer and 2 is equal to 100. Please write back if you have any other questions. - Doctor Patti, The Math Forum http://mathforum.org/dr.math/
