I need help with decimals 2.1 x 5.01?
A simple trick with multiplying decimal numbers is to remove the decimals, multiply the two numbers, then add the decimals back in. The number of decimals you add back in is the total number of decimal places. For example, the stated problem has 1 decimal places in 2.1 and 2 decimal places in 5.01. So first we do the following: 21x501=10521 Now we add 1+2=3 decimal places into the result above: 10.521 That's the answer.
What are the 2 numbers between 0 and 1 in decimals in math?
Actually, there is an infinite number of decimals between 0 and 1.
How many numbers can you make with four digits?
Whole numbers . . . All of the counting numbers from 1,000 to 9,999 = 9,000 of them. Fractions . . . -- all numerators from 1 to 9 / all denominators from 100 to 999 = 8,100 -- all numerators from 10 to 99 / all denominators from 10 to 99 = 8,100 -- all numerators from 100 to 999 / all denominators from 1 to 9 = 8,100 -- Total fractions = 24,300 Decimals . . . -- All whole numbers from 1 to 9 plus all 3-place decimals from 0.100 to 0.999 = 8,100 -- All whole numbers from 10 to 99 plus all 2-place decimals from 0.10 to 0.99 = 8,100 -- All whole numbers from 100 to 999 plus all 1-place decimals from 0.1 to 0.9 = 8,100 -- Total decimals = 24,300 So far, we have a total of 57,600 numbers. But this is way off, for two reasons that I can think of just now: 1). I have not even considered mixed numbers ... combinations of a whole number and a fraction. Including those would increase the total. 2). Many of the fractions, decimals, and whole numbers constructed in the above way would be equal to each other. So, that figure of 57,600 must be seen as a rough approximation of a ballpark order-of-magnitude estimate. The refinement is left as an exercise for others, because like a bad investment, I have lost interest.
Are decimals whole numbers or rational numbers?
Rational numbers. Whole numbers are numbers such as 1, 10, 25, etc.
Is composite number divisible by 1?
of course all numbers are divisible by 1 expect 0 and numbers that have decimals
When is the sum of two decimals a whole number?
When the fractional parts, if any, of the two decimal numbers sum to 1.
When is the product of two decimals less than both factors?
when the numbers are between 0 and 1
When is the sum of two decimals equal to a whole number?
This will happen if the fractional parts of the numbers sum to 1.

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.
