How do you determine if a fraction is in simplest form?
if the fraction's numerator and denominator cant be divided by any number remembber both numerator and denominator must be divided by the same number
Why cant you assume that a number is irrational because it is expressed using the square root symbol?
Well, for example, the square root of 4 is 2, which is a rational number. As long as the number which is being square rooted is not a square number itself (i.e. 1, 4, 9, 16 etc.), then it will be irrational. So..... the square roots of 49, 100, 196, for example, are all rational numbers (7, 10 and 14 respectively.) They do not have to be integers. The square of of any rational number automatically has a rational square root eg the square root of 77.41792 is 77.4179 . Rational means expressable as a ratio of integers: 77.4179 is 774179/10000 .
What is the mathematical symbol for an irrational number?
it's Q Bar. i cant find a symbol for it on the keyboard. but its basically like The rational Symbol (Q) with a horzontal line on top of it.
Can prime numbers be equal?
How can 2 prime numbers ever be equal They cant be Equal.
How do you convert fractions to simple forms?
Divide them each by the same number. Ex. 2/4 can be divided by 2 each so you get 1/2. If you cant divide the numerator and the denominator by the same number then the fraction is already at it`s simplest form!
How do you know if 2 is a rational number?
first you think that is 2 a repeating decimal.... and can u reduce it if its not a repeating decimal and u cant reduce it then it is a rational number

Can a mixed number be equal to 2?
no it cant
Is 0.151155111555.Rational Or Irrational?
This number is rational as 0.151155111555 = 151155111555 / 1000000000000 = 151291 / 1000899 if 0.151155111555 is the beginning of the number 0.151155111555111155551111155555.... then it's irrational as the decimals are not repeating and the sequence is infinite
How do you simplify a mixed number with improper fraction?
Divide the denominator (bottom number) into the whole number , and then add that to the numerator (top number) . if you cant sinplify, leave it...
Is -5 a rational number?
Yes.-5 is a rational number. It's the ratio of 5 to -1 .
Can a number be irrational and rational at the same time?
No they cant because that would be contradicting each other ( The numbers wont end and don't have a pattern but rational is the complete opposite)
Can the difference of two rational numbers can be irrational?
No irrational numbers don't have patterns and cant be expressed as a ratio so you cant even subtract the number. Ex: 22/7 - sqrt(2), you wont be able to find the difference since you cant even put it in a complete number.
How do you write a fraction to the lowest form?
you divide both the numerator and the denominator by a number they both go into and you keep dividing until you cant anymore.
Can the denominator of a rational number be zero?
Josh mows lawns. He wants to pick up some customers but wants to know how long it will take before saying yes to all of them. He mows 3 of the lawns in 72 minutes. Write an equation that will allow Josh to calculate the time it would take to mow any given number of lawns.
Why cant you add the numerator and denominator?
You can but it makes no mathematical sense.
