I have a question that asks which of the following is the number 78.5
Integer
Rational
Variable
Constant
Thanks for any help.
The number 78.5 . . .
is not an Integer because it is not a whole number.
is a Rational number because it can be expressed as the ratio of 2 numbers (157/2)
is not a Variable because it is a defined constant number.
is a Constant because it is defined and unchanging number.

78.5 is a decimal number, and you can transform it in a fraction like:Originally Posted by Suriya
785/10.
78.5 is a constant because its value doesn't change.
Integers are whole numbers (without decimal point) like -13;35;0;76 and so on.
A variable is something that changes, the temperature of your room, for instance, the speed of a car etc.
