list the following rational numbers in order from least to greatest. -0.4 , 0.48, 4/8, -4/8. Someone plssssssss help me I need it for today.

Answers

Answer 1

Answer: For a problem like this, it is best to convert all numbers to a similar form making them easier to compare. I am going to convert them all to decimals, although converting them all to fractions can also work.
-0.4 is already a decimal, so it needs no conversion; the same goes for 0.48.
4/8 is equal to 1/2, which equals 0.5 as a decimal. -4/8 is the same as -1/2, which is -0.5.
Therefore, we are left with the following converted numbers:
-0.4; 0.48; 0.5; -0.5

Now to simply order them from least to greatest, we will start with the two negative numbers because they are both below zero. When comparing negative numbers, the "bigger" one is actually smaller because it is farther below zero. Therefore, -0.5 is the smallest, followed by -0.4.

Now for the last two, 0.5, or 0.50, is 0.02 bigger than 0.48. Therefore, 0.48 is the second largest number and 0.5 is the largest.

This is the order now:
-0.5 (smallest)
-0.4 (2nd smallest)
0.48 (2nd largest)
0.5 (largest)

Now they simply need to be converted back to their original form (if applicable):
-0.5 = -4/8
-0.4 = -0.4
0.48 = 0.48
0.5 = 4/8

This leaves us with the answer:
-4/8; -0.4; 0.48; 4/8

Order the following from least to greatest -8,-19,0,1/2,1/4

Answers

Obviously 0, 1/4 and 1/2 are bigger than the previous 2 numbers. We start with -19 because that is the smallest number there is in this group. The next one we go with is -8. We chose these two because they are negative. 0, 1/4 and 1/2 are next. 1/4=0.25 1/2=0.5

So the answer would be -19, -8, 0, 1/4, 1/2

What is greater , 42,000 mg or 24 g?

Answers

mg=miligrams=1/1000 gram
so conversion factor is
1g/1000mg
mulriply 42,000mg by 1g/1000mg
units cancel and you are left with
42g
42 g and 24 g
42 is greater than 24g so

42,000 mg is greater

42000 mg is greater
Hope this helps! :)
