For the following set, which number has the largest absolute value?
4, –1, 12, –20, 19, 0
answer -20
is this correct?
-20 does have the greatest absolute value.
19
No Emma
│19│ = 19 but
│-20│ = 20 , which is greater than 19
so Brianna was right
Yes, that is correct. To find the number with the largest absolute value, you need to compare the absolute values of each number in the set.
To determine the absolute value of a number, you remove the negative sign (if there is one) and consider only the magnitude.
In this case, comparing the absolute values of each number, we have:
|4| = 4
|-1| = 1
|12| = 12
|-20| = 20
|19| = 19
|0| = 0
Among these absolute values, the largest one is 20, which corresponds to the number -20 in the original set. So, you are correct that -20 has the largest absolute value in the given set.
