Example Question #1 : How To Compare Integers In Pre Algebra
Which of the following numbers is the greatest?
When comparing negative numbers, it is important to remember that the numbers with the larger absolute value (greatest numerical term) are actually more negative. Though it seems that would be the largest number in this case, it is actually the smallest, as it is the farthest down the number line in the negative direction. The greatest number is the one with the smallest absolute value, which is .
Remember, also, that zero is greater than any negative number!
Example Question #1 : How To Compare Integers In Pre Algebra
Given that is an odd integer, which of the following must produce an even integer?
An easy way to solve this problem is to define as 1, which is an odd integer. Plugging in 1 into each answer yields as the correct answer, since
4 is an even integer, which is what we are looking for.
Example Question #2 : How To Compare Integers In Pre Algebra
Which number is greater?
or
It cannot be determined from the information provided.
They are equivalent.
When comparing negative numbers, recall the number line. Numbers that are "more negative", or negative with a large absolute value, are really very small. Thus, comparing negative numbers can sometimes seem counterintuitive. In this case, since we are comparing two negative numbers, the number with the larger absolute value is actually the smaller number. Therefore, the greater number is .
Example Question #3 : How To Compare Integers In Pre Algebra
Which of and is larger?
Neither
Recall that when comparing negative numbers, those numbers that are "more negative" are actually further to the left on the number line and thus are smaller. Therefore, even though , we have that .
Therefore is larger.
Example Question #4 : How To Compare Integers In Pre Algebra
Place in order from smallest to largest:
Find the least common denominator (LCD) and convert all fractions to the LCD. Then order the numerators from the smallest to the largest
So the correct order from smallest to largest is
