For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.
Answer:
2 1/20
Step-by-step explanation:
It was trick math problem and I was working it out, so mad I didn't pay attention to the numbers more closely. :)
There are two 3/8 but one is negative so they cancel each other out
So you have now (-4/5) + 5/4
Find the least common multiple they have.
In this case 20
-4/5 = x/20 = 16/20
5/4 = x/20 = 25/20
So now add them both together
16/20 + 25/20 = 41/20
Find the least common factor for both the denominator and numerator of 41/20
41 is a prime number so
41/20 is an improper fraction
Divide 41 by 20 to get 2 1/20
Answer:
56
Step-by-step explanation:
Given that Lydia is painting flower vases.
Paint required for painting one flower case = 3/16 quart
total paint available with Lydia = 21/2 quart
We have to find the no of flower cases that can be painted.
This is a problem of direct variation since when no of flower cases increase paint required also increases.
3/16 quart for 1 flower case
Hence 21/2 quart for 21/2 divided by 3/16
= 21*16/(3*2) (by rule for fraction division)
= 7(8)
= 56
The answer is 5/2
y2-y1/x2-x1
9-4/7-5 = 5/2
Well, I wasn't down in Georgia for my 7th grade, but my mom told me before that it helps you to see how your progress is. No need to be worried :) You've got this!
