How many 4 digit numbers can are there with distinct digits?

How can you simplify a ratio?
Find a common number that you can divide both by, just like simplifying fractions. Say you have a ratio of 2:4. Both of those numbers are divisible by two, so if you divide both by two you get 1:2. Generally you want to have both numbers as whole numbers (i.e. no fractions or decimals) Find the GCF of the numbers and divide them both by it. If the GCF is 1, the ratio is in its simplest form. If the ratio is between two decimals, multiply them by whatever power of ten will eliminate the decimals. Then proceed with the GCF.
How can you estimate sums or differences of decimals?
In the same way as you estimate them for whole numbers.

0.235 * 0.6891 = 0.1619385 What's to estimate? The total decimal places in the multiplicands is the total in the answer.
Why is estimating important when dividing with decimals?
Using an estimate ensures that the answer is about right. With decimals where the decimal point should go is difficult for a lot of people, so an estimate of the answer ensures that it is put in the right place.
How do you convert decimals into decimals?

What are signs for decimals?
