What is the correct ordering of these numbers on a nummber line from left to right -2.5,0.5,-3,-1
Yes, if you are comparing the number to itself.
Only if you are comparing a number to itself. The GCF and LCM of 10 and 10 is 10.
They are used for working out equations where the numbers you are working with are not physically possible, but we just imagine they are, such as the square root of a negative number In engineering, especially Electrical Engineering, using complex numbers to represent signals (rather than sines and/or cosines) make comparing and working with signals easier.
Common factors are found by comparing the factors of sets of numbers. The common factor of any group of consecutive numbers is 1. I suspect you might want to know the factors of those numbers rather than the common factors. If so, ask that question. It has been answered here many times before.
place value :)
You do not, but it is easier.
Rational numbers are roots, decimals, fractions, and whole numbers. Bascially anything that can become a decimal. Irrational numbers are like pi. I'm pretty sure to be irrational, they have to repeat. Anyway, ordering them and comparing them means looking at them and seeing which is smallest and largest. Then you order them (smallest to largest or whatever it says).
This answer is irrelevant because you did not explain yourself, the correct answer is,"Its important so you can separate whole numbers for parts of whole numbers."
They are similar because when you compare decimals you say the larger one has more value so the decimal is larger like in comparing whole numbers the number that has more value is larger. So they are very similar.
Convert them all to their decimal equivalents (by dividing each numerator by its denominator), then you can easily see which numbers are greater than others.
Lining the numbers up makes it easier to spot 0s between the decimal point and the leading non-zero digit.
Ordering numbers is arranging the numbers in a particular order to make comparison easier. Example: 11, 2, 5, 8, 9, 11, 6, 44, 6 are the numbers in a given list. Ordering the list from smallest to highest: 2, 5, 6, 6, 8, 9, 11, 11, 44. From the list, how many are greater than 8? Answer: 4 are greater than 8 (9, 11, 11, 44). When the numbers are ordered it makes comparison easier.
To order fractions and decimals, you can either write them all in the same form and then compare them, or place them on a number line. Recall that numbers increase in value as you move from left to right along a number line.
the operations that can be used in comparing two numbers are??????
it separating the whole numbers from the fraction parts.
