In each of the following, order decimals from least to greatest

a.24,9419, 24.942, 24,94189, 24.94199
b.-34.25, -34.251, -34.205, -34.2519

a. 24.94189, 24.9419, 24.94199, 24.942

b. -34.2519, -34.251, -34.25, -34.205

Are you sure that you don't have a typo in the last quantity?

To order decimals from least to greatest, you need to compare their values. Here's how you can do it for each of the given options:

a. 24.9419, 24.942, 24.94189, 24.94199:
- Start by comparing the whole numbers before the decimal point. Since they are all the same (24), move on to the decimal places.
- The first decimal place to compare is the thousandth place (the number after the first decimal point). In this case, we have 9419, 942, 94189, and 94199.
- The smallest value in the thousandth place is 942. It comes first.
- Next, compare the hundredth place (the number after the second decimal point). We have 9419, 94189, and 94199.
- The smallest value in the hundredth place is 9419. It comes next after 942.
- Finally, compare the ten thousandth place (the number after the third decimal point). We have 94189 and 94199.
- The smallest value in the ten thousandth place is 94189. It comes next after 9419.
- Therefore, the order from least to greatest is 24.942, 24.9419, 24.94189, 24.94199.

b. -34.25, -34.251, -34.205, -34.2519:
- Start by comparing the whole numbers before the decimal point. Since they are all the same (-34), move on to the decimal places.
- The first decimal place to compare is the hundredth place. In this case, we have 25, 251, 205, and 2519.
- The smallest value in the hundredth place is 205. It comes first.
- Next, compare the thousandth place. We have 25, 251, and 2519.
- The smallest value in the thousandth place is 25. It comes next after 205.
- Finally, compare the ten thousandth place. We have 251 and 2519.
- The smallest value in the ten thousandth place is 251. It comes next after 25.
- Therefore, the order from least to greatest is -34.205, -34.25, -34.251, -34.2519.
