Answer:

Option C

Step-by-step explanation:

We know that in a number line numbers all (rational preferably) would be marked on a line in a chronological order.

Mid point of A and B would be the average value of A and B.

Here given that mid point is 2 1/2

This implies average of A and B is 2 1/2

Or total of A and B should be 5

Out of 4 options let us check which gives total 5.

A) (2,3) .. Total is 5

B) (-4,9)..Total is again 5

C) (-4,8)..Total is not 5 but 4

D) (-0.75, 5,75) .. Total is 5

So out of these 4 options only C would not describe a situation where the midpoint between points A and B is 2 1/2

HELP I NEED THIS DONE QUICKK CAN ANNYONE HELP???????????????????????????????????????????????????????????????????????????????????

natulia [17]

For the first question, it would be D: $\frac{1}{3}$ ÷ 9. This is because to solve a division problem with fractions, you would need to multiply the first fraction by the reciprocal of the second fraction. For the second question, the answer would be D: 32. This can be solved by dividing 8 by $\frac{1}{4}$ or 0.25. For the third question, it would be D. $\frac{1}{12}$ . This can be solved by dividing $\frac{1}{4}$ by 3. For the fourth question, the answer would be $\frac{1}{12}$ . This can be found by flipping the 4, which would make it look like $\frac{1}{4}$ , and multiplying it by $\frac{1}{3}$ . For the last question, 1 would be B, 2 would be C, 3 would be C, and 4 would be A.

Hope this helps ^-^
