1). Any number that you can write down completely, using digits, decimal point, and fraction bar, is a rational number. So yes, 5/7 is rational. 2). Any number that can be written as the ratio of two whole numbers is rational. 5/7 is the ratio of 5 to 7. So yes, it is rational.
1 over 6 and many others...
Yes - the proper fraction 7/19 is a rational number.
Yes.
Yes. Any rational number divided by another rational number is also rational.
Yes, -5/7 is a rational number because it can be expressed as a fraction.
5/7 is a real number and a rational number.
-7/8 < -5/6 (a+)

If the decimal number can be expressed as a fraction (with one whole number over another), then it is a rational decimal number. So 7/5 is a rational number, and remains as such even if expressed in decimal form (of 1.4).
Rational
Yes, because 7+5 = 12 which is a rational number
1 over 6 and many others...
Rational.
Well, honey, a rational number is any number that can be expressed as a fraction where the numerator and denominator are integers. So, yes, 15 over 7 is a rational number because it can be written as 15/7, where both 15 and 7 are integers. But remember, just because it's rational doesn't mean it's always logical!
5/4x+7/12x is the same as 15/12x+7/12x = 21/12x
