No. An irrational number is any number that is not a rational number; A rational number is any number that can be expressed as one integer over another integer. negative 3 over 4 is one integer (negative 3) over another integer (4), and so is a rational number.
Yes. Any number that can be written as one integer over a non-zero integer is a rational number. 2 3/5 = (2×5+3)/5 = 13/5 which is the form of one integer over a non-zero integer, thus it is rational.
4/15 is the most reduced form of that fraction with integer numerator and denominators.
3 over five 2/3 = 10/15, and 3/5 = 9/15. 2 over 3 (10/15) is obviously bigger than 3 over 5 (9/15).
1 over 3 is a third. A third of 15 equals 5 (3 x 5 = 15)
An integer is a number, positive or negative. So 15 is an integer.
90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.
No, an integer is a WHOLE number
Yes. 6 over 2 is the same as 3, which is an integer.
No.
No.
156 is an integer and there is no sensible way to express it as a mixed fraction.
Rational yes, integer no.
Yes it can be. (the number 3 is an integer).
15
The middle integer is 45/3 = 15. The other two are 15-2 and 15+2 ie 13, 15 and 17
The statement is not true. Disprove by counter-example: 3 is an integer and 5 is an integer, their product is 15 which is odd.
