What is this from least to greatest
-8.2,0.4,-2 1/2,2.4
I got 0.4,-2 1/2,2.4.-8.2
look at a number line.
The number farthest to the left is the smallest, so
-8.2 <---- smallest
etc
you have (almost) listed them in order of distance from zero, but smallest means farthest to the left.
And even then, 2.4 is closer than 2 1/2
To arrange these numbers from least to greatest, you can use a method called sorting. Here's how you can do it:
Step 1: Start with the given numbers -8.2, 0.4, -2 1/2, and 2.4.
Step 2: To compare the numbers accurately, it is helpful to convert the mixed fraction -2 1/2 to a decimal. When converted, -2 1/2 becomes -2.5 since 1/2 is equivalent to 0.5.
So the numbers become: -8.2, 0.4, -2.5, and 2.4.
Step 3: Look for the smallest number. In this case, it's -8.2.
Step 4: Next, find the next smallest number, which is -2.5.
Step 5: The next smallest number is 0.4.
Step 6: Finally, the largest number is 2.4.
Therefore, the numbers arranged from least to greatest are: -8.2, -2.5, 0.4, 2.4.
