Answer:
The arithmetic mean is 10.9
Step-by-step explanation:
In this question, we are tasked with calculating the arithmetic mean using the information given.
The arithmetic mean or otherwise called the average is the sum of all the values in a given set divided by the number of elements or count of the elements in that particular data set
Mathematically, the arithmetic mean can be found by dividing the sum of the data values by the number of data values.
In equation form, we have 
Inserting the values, we have Arithmetic mean = 10998/1007 = 10.92 which is 10.9 to the nearest tenth
What is the digit at the hundred thousands place? It is 2. Is the digit to the right of it less than 5? No, 5 is 5. So replace the digits to the right of 2 with 0, and change the 2 to 3.

Answer:
949
Step-by-step explanation:
3/4 = 21/28 after multiplying top and bottom of 3/4 by the value 7
3*7 = 21 and 4*7 = 28
The goal is to get 3/4 into an equivalent fraction that has 28 as the denominator.
------------------------------------
So 3/4 - 1/28 is the same as 21/28 - 1/28
The denominators are the same. We subtract the numerators to get 21-1 = 20. The denominators stay the same at 28
We have
21/28 - 1/28 = (21-1)/28 = 20/28
Now reduce 20/28 as much as possible. Divide both parts by the GCF 4
20/4 = 5
28/4 = 7
The final answer is 5/7
