Yes
Yes because rational numbers can be expressed as fractions
Yes, it is.
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).
Yes.

2
is 5 over 7 a rational number
Yes, 28 over 5 is a rational number. A rational number is any number that can be expressed as a fraction where the numerator and denominator are integers. In this case, 28 over 5 can be written as the fraction 28/5, where both 28 and 5 are integers. Therefore, 28 over 5 is a rational number.
-0.5 is a rational number. It can also be written as -5/10
Yes. Any rational number divided by another rational number is also rational.

3.14 is a rational number. When divided by 5, another rational number, the result is still rational. In its most reduced form, we have (3.14/1)/5 = (314/100)/5 = 314/500 = 157/250 - a rational number
No. Any fraction with integers in the numerator and in the denominator is, by definition, RATIONAL.
