It's not. It's the ratio of 123 to 1,000 ... a perfectly rational number.
yes
Yes. The sum of two irrational numbers can be rational, or irrational.
.0123 is closer to zero than .023. If you round it to hundredths, it would be .01 or .02. Its easier to think of this way. 1 is closer to zero than 2.
Not necessarily. The sum of two irrational numbers can be rational or irrational.
Yes normally but if both irrational number are the same then the quotient will be 1
0123 is treated as octal so o123=83(decimal equivalent) diffrence is 123-83=40
fraction for 0.0123 = 123/100000.0123 * 10000/10000 = 123/10000
Is a series of number
my book says code 0123 THROTTLE/PEDAL POSITION SENSOR/SWITCH A CIRCUIT HIGH INPUT
0123 456 789
Irrational. Irrational. Irrational. Irrational.
In general, you enter a number to text exactly the same way you would dial the same number for a voice call from your mobile phone. For example, if you are in (fictional) area code 999, sending a text to (999) 555-0123, you might enter the number as 555-0123, 999-555-0123, or even +1 999 555 0123 (international format). It makes no difference to the cost of the call or text.
It is irrational.
Rational
Such a sum is always irrational.
If it says "negative irrational", then obviously it is irrational.
