This is kind of a hard one to explain so bear with me.

Step-by-step explanation:

What this question is saying is that Mark thinks the equation is true. All we need to do is to figure out what M could equal.

What you need to do is plug in a random number to replace M in the equation. Then, evaluate that equation and see if the solution you get for the fraction on the left is greater than or equal to 2/3.

If its not, then you can put it at 4B since it does NOT support Marks claim. If it does, then put it in 4A because it DOES support Marks claim.

For example, you could replace M with 2. That would make the fraction on the left 10²/15².

10²= 100

15²= 225.

That would make the fraction 100/225

100/225 simplified is 4/9.

Then, you would have to determine if 4/9 is greater than or equal to 2/3. Converting the fractions into decimials makes it much easier.

4/9 = 0.444

2/3 = 0.666

This means that 4/9 IS NOT greater or equal to 2/3

So, if M=2, the equation is NOT true. Therefore, you would put the number 2 in 4B because 4B is asking for a number that does NOT support Marks claim.

I really hope this helps, this took ages to write.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
