There are 6 times as many dogs as cats. If the total number of dogs and cats is 21. How many dogs are there? Show your work
Answers
there are 3 cats and 18 dogs. :D
I say divide 21 with 6 and you get 3.5 so round it and you get 3.Then subtract 3 from 21, so the answer is 3 cats ad 18 dogs.

If your pencil is 20 cm long how many millimeters is it
Answers
For this, you have to know the unit conversions. For metric, this is somewhat easier to remember. cm = centimeters. centi means 100th. One way to remember this one is that a cent is 1/100th of a dollar. So also is a centimeter 1/100th of a meter. A millimeter is 1/1000th of a meter. so a centimeter is 10 millimeters.
Therefore the solution is 200 millimeters.
