My son came home with a math quiz and the teacher marked one wrong. He has 100 as the answer but the teacher says the answer is 1000. Please help me settle this because my son is upset and I thought the answer was 100 too.

1 decimeter = 10 centimeters = 100 millimeters
its a prefix thing--- the teacher is right-- tough luck. It is one of them things that you just memorize

A millimeter is 1/1000 of a meter. A decimeter is 1/10 of a meter. The ratio between the two is 100 millimeters to 1 decimeter. A millimeter is 1/100 of a decimeter. If the question was posed as you have phrased it here, the teacher is incorrect. The correct answer is 100.
I'm a teacher too. Ask the teacher to work through the problem with you, the mistake should become obvious. We all make mistakes sometimes, even teachers.

I tried to make 1000 work, but I'm pretty sure it's 100. Try it with fractions (and knock a decimal place off of each to simplify it.) 0.1 vs .001 would be 1 vs .01 if you simplified it. 1/1 vs. 1/100. So multiply it by 100, and you get both sides equalling 1. So the answer is 100. Now, a decimeter *is* a 1/1000th of a meter, but a decimeter is 1/10 of a meter. The only way this would work is if the question was about a *dekameter* and a millimeter (a dekameter would be 10 meters.) Was there a typo between deci and deka? Did they even talk about deka in his class? What a strange question. I'm imagining little loops under numbers...no! Don't make me go back there! It's 100. Or I'm completely confused.

I was taught that a decimeter is smaller than a millimeter so I really can't help you there.

I think the answer is 100.

the answer is 100....have the teacher explain how they got 1000, he'll see his mistake and hopefully correct your sons paper...I'm a teacher..don't go in with guns blazing.. you do better with a subtle approach.

I would think 100, cause you move to place, but that is moving the wrong way, I think. I think the answer should be .001, but she said one thousand so i am off.
