Which of the following is a rational number but not an integer?

188, 13 2/5, -4, or -51

Option C

Step-by-step explanation:

Rational numbers are numbers of the form p/q, where p and q are integers and q not equal to zero.

Integers are number of the form p/q , where q = 1

Option A : 188 => integer and rational

Option  B: 13   =>  integer and rational

Option C :2/5  =>  rational but not integer ( because q = 5 and not 1 )

Option D : - 51 => integer and rational

Step-by-step explanation:

As,

Integers includes whole numbers, and negative of the whole numbers.

And Rationals includes every fraction, Integers and negative fraction.

So,

188, -4, and 51 are both Integers and Rationals.

But,

Only 13 2/5 is a mixed fraction included only in rationals and not in Integers

depending on others is critical to survival. my source is apex!

step-by-step explanation:

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
