Add 1 5/6 + 4 3/4. Write the answer in simplest form and leave the result as mixed numbers

Step-by-step explanation:

1 5/6 + 4 3/4=11/6+19/4=(22+57)/12=79/12=6 7/12

6 and 7/12

Step-by-step explanation: To add mixed numbers, first add the fractions.

Since 5/6 and 3/4 are unlike fractions, we first need

to find a common denominator, which in this case is 12.

So we multiply the numerator and

denominator of 5/6 by 2 to get 10/12.

We will also multiply the numerator

and denominator of 3/4 by 3 to get 9/12.

Now we can add the like fractions, 10/12 + 9/12 to get 19/12.

Next we add the whole numbers, 1 + 4 is 5.

19/12 means 1 and 7/12 so we have 5 and

7/12 + 1 and 7/12 which is 6 and 7/12.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
