The coreect point is (4,7)
Every whole number<span> is a </span>rational number: for example, 3=31. ... Everywhole number<span> n can be written as a fraction of integers: n=n1. We aren't required to write it that way; we just need to know that it is possible to express every </span>whole number<span> as a fraction of integers, and hence it is </span>rational<span>.
So I Believe the Correct Answer would Be D)</span><span> If a number is not a rational number, then it is not a whole number. The converse is true</span>

In this graph the instantaneous velocity=decline.
You just have to do this:
And the answer is letter (A)
<span>1). 16 x 3/4
Step One- 16/1 x 3/4
Step two- 4 goes into 16 four times so cancel the 4 and change the 16 to a 4...
Step three- 4 x 3=12
2). (81/16) divided by (9/14)
Step one- Since its division we use (FREEZE CLAP FLIP)= Freeze (81/16) Clap the division sign and change it to a multiply sign and Flip the riprocals (9/14)
The equation is now 81/16 X 14/9
Next 81 is divisible by 9 and 16 and 14 are divisible by 2
So the new formula i s 9/8 X 7/1
Solution=63/8
3). 2/3 divided by 4/3
Flip the reciprocals for the 4/3
New equation is 2/3 X 3/4
2 and 4 are divisible by 2 and the 3's cancel each other out
Solution: 1/2</span>
