An irrational number can become rational by dropping a few decimal places.
Ans 2.
An irrational number can produce a rational by being truncated as desired.
The square root of 2 is often truncated to 1.414, and is useful in all sorts of technologies at that accuracy. However, it is no longer the square root of 2 !
It is often a useful approximation, but to a mathematician it is a queer duck.

How do you rationalize a denominator?
You multiply the numerator and the denominator by the same expression - and do it in such a way that the denominator becomes rational.Example 1: The denominator is square root of 5, which I will call root(5). If you multiply top and bottom by root(5), the denominator will become rational. Example 2: The denominator is root(2) + root(3). If you multiply top and bottom by root(2) - root(3), then the denominator will become rational.
Why do numbers become a repeating decimal when divided by 9?
Numbers become a repeating decimal when dividing by ANY whole number, except when (if the division, expressed as a fraction, is in simplest terms) the denominator has no prime factors other than 2 and 5.The reason for this is related to the fact that our decimal system is base 10, and 10 is made up of the factors 2 and 5. Any denominator with other factors cannot be exactly expressed as a terminating decimal. That includes denominators 3, 6, 7, 9, 11, 12, 13, 14, 15, 17, 18, 19, 21, etc.
Eight to the negative fourth power?
Whenever you have a number to the negative power, the number would become a fraction so that the power could be positive: 8-4 = 1/84 which results in 1/4096 = 2.4414x10-4 (decimal form)
What is 3 percent of 11 million?
I'd start by figuring 1% of 11 million, and then tripling that answer. To get 1% of anything, move the decimal two places to the left. So 1,000,000. will become a "1" followed by 4 zeros, not 6 zeros. That's 10,000. Ten thousand. Triple it = thirty thousand.
How does changing the slope of a linear function affect its graph?
It rotated the line about the point of intersection with the y-axis.
Can an irrational number become rarional by dropping a few decimal points?
Well, not 'a few'. An irrational number can never be completely written out.As a decimal, it just keeps going and going, forever. If you stop it anywhereand say "That's the number.", then you have a rational number.
What happens to the value of a number when multiplied by a decimal?
Nothing special happens. The answer can be smaller or bigger. A rational can become irrational or the other way around.
What is comparing and ordering rational numbers?
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).
Is decimal a rational number?
It depends. A terminating decimal is a rational number. A decimal which, after a finite number of places, becomes a repeating (or recurrent) decimal is also a rational number. A decimal that is not terminating, nor [eventually] settles into a recurring pattern is not a rational number. Note that the decimal need not become recurring immediately.
Can an irrational number become a rational number?
How would you do that ?? You'd have to change the value of the number. As long as the irrational number keeps its original value, it's an irrational number.
When a rational fraction is divided to form a decimal value it become a terminating or what decimal?
finite
What is rational behavior?
a person's past experiences shape their belief system and thinking patterns. People form illogical, irrational thinking patterns that become the cause of both their negative emotions and of further irrational ideas.
True or false an irrational number can become rational by dropping a few decimal places?
In This Case, the answer is false and this is why in the case you have the Square root of 3, or (√3) To Approximate this, you come up with a number near to 1.7320508075688772935274463415059... and so on this is irrational because it is non-repeating, or you cannot simply make a fraction of it. But, if this where true, the you would be saying this 1.7320508075688772935274463415059=1.732=1.7.... and, in math, this is not true a more simple explanation would be that if you had 1/3 and 3/10, which would you say is bigger? 1/3 is bigger, and here is why 3/10=0.3 1/3=0.333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333333...... and so on but, if you slap all of those 3's off there, it becomes 0.3, making it "rational", but incorrect. -Nick Ogre

What kinds of decimals will fractions turn into?
Rational numbers will become either a terminating decimal (if the denominator has prime factors of 2 and/or 5 only) or a decimal that recurs one or more digits (possibly after one or more digits that do not recur). Examples: 1/2 = 0.5 (terminates) 1/3 = 0.333.... (3 recurs) 1/6 = 0.1666.... (6 recurs after the initial non-recurring 1) 1/7 = 0.142857142857142857.... (142857 recurs)
Why do numbers get bigger when you divide a decimal?
This has absolutely nothing to do with decimals. For example, any positive number become smaller if divided by any number that is greater than 1: whether in rational form or decimal form.
