It is equal to 21/2 which is a rational number
4/3 is irrational because it is as follows 4/3=1.333 (1.333 continuing )
Well, honey, a rational number is any number that can be expressed as a fraction, where the numerator and denominator are both integers. So, if you can write 15 over 4 as a fraction (15/4), then yes, it's a rational number. Don't stress, math can be a real pain in the behind sometimes, but this one's a no-brainer.
Any number that can be written as a fraction is rational -- therefore, 4/9 squared is rational (it can still be written as a fraction even if you multiply it by itself).
It is a rational number
Rational.
Yes, 3/4 is a rational number
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. It's the ratio of -144 and 4. That makes it a rational number by definition.
4.7 is already a rational number. If you mean as a mixed number, this is equal to 4 7/10 or four and seven tenths.
Any number that can be expressed as a fraction is rational. So yes.
.4/.8 is the same as 1/2 which is a rational number
Yes, 3.4 is a rational number between 3 and 4: 3.4 is between 3 and 4, and 3.4 = 34/10 = 17/5 which is a rational number. The rational number midway between 3 and 4 is 3.5
TRUE
Yes.
No, the number 38.4 is a rational number. It can be expressed as a fraction, which is a characteristic of rational numbers. 38 4/10, or 384/10.
4 is a rational number. Any number is rational as long as it can be put into a fraction or ratio. In other words, 4 is a rational number because if you want to express 4 as a fraction, you would just put it over 1; 4 is the numerator, and 1 is the denominator in this case.
