Answer:
B decrease
Step-by-step explanation:
First, lets put the numbers in order from greatest to least.
10 9 9 8 6 4 4
Second, let's find the median without number 1. (The median is in bold.)
10 9 9 8 6 4 4
Third, let's add the number 1.
10 9 9 8 6 4 4 1
Fourth, let's find the median with the number 1.
10 9 9 8 6 4 4 1
Since there are two numbers in the middle let's find the average between them.
8+6=14
14/2= 7
Last, let's compare the two medians.
8>7
So when you add the number 1 the median decreases. So your answer is B decrease
Step-by-step explanation:
To multiply the fractions, like

Multiply the top,

To divide fractions, like

You take the top number,

Then you flip the bottom number,

Then multiply the two

And that is your answer. Comment if you need more clarification
