Answer
Good question!
A. false. Even though 5 is usually greater than 2, in this case it is less because it is negative and positives are always greater than negatives.
B. true. Just like the last question, positives are always greater than negatives and even though 8 is usually greater than 3, in this case the 3 is a negative so it is less.
C. true. Think about which number is closer to the number line. When we are talking about negative numbers, the number closer to the number line is greater.
D. false. Same concept as the last question where -12 is closer to the number line than -12.5 so -12 is actually greater.
If you have any additional questions feel free to ask me or your teacher so you can really master what you're learning. :)
To be able to compare 2 fraciton we have to make common denominator and then we can just compare numerators.

Now we can compare numerator from the first (9) and from the second fraction (8)
9>8, so the bigger is 9/10
The last one would be negative.
Positive times positive = positive
Positive times negative = negative
Negative times negative = positive
So basically, if there is an odd number of negatives, then it'll end up negative, with some exceptions.
So now we know it has to either be the first one or the last one.
The first one is multiplied by 0, so it can't be that one.
So it has to be the last one.
Answer:
10 and 11
Step-by-step explanation:
Let the first integer be x.
Then the next one, since it's consecutive, must be (x+1).
The two equals 21. Thus:

Combine like terms:

Subtract 1 from both sides:

Divide both sides by 2:

So, the first integer is 10.
And the second integer is 10+1=11.
