order from lest to greatest:

6 7/8, 6 15/16, 6.9, 5,3

Change the fractions to decimals. I'll be glad to check your answer.

how do you change a mixed number into a decimal?

Change the fraction to a decimal by dividing the numerator by the denominator.

6 15/16 = 6.94

but what would 6 7/8 be??

Do it the same way.

To order the given numbers from least to greatest, you need to compare their values.

Let's convert all the numbers to decimals for easier comparison:

6 7/8 = 6 + 7/8 = 6 + 0.875 = 6.875
6 15/16 = 6 + 15/16 = 6 + 0.9375 = 6.9375
6.9 remains as it is.
5.3 remains as it is.

Now, let's compare the values:

5.3 < 6.875 < 6.9 < 6.9375

So, the numbers in order from least to greatest are: 5.3, 6.875, 6.9, 6.9375.
