**Ms. Sue**, Monday, January 31, 2011 at 9:42pmThese are not college or high school problems. They are part of the normal 5th grade curricula.

Check this site for LCM instructions.

Let x = the number of boys in the class.

36 - 16 = x

**Writeacher**, Monday, January 31, 2011 at 9:54pmI agree with Ms. Sue. These are definitely in a good 5th grade math curriculum. My granddaughter is in 5th grade this year, and she has had this level of work for over a year now.

**pat**, Monday, January 31, 2011 at 9:58pmcan you show how to do the median ?

what is the median for the following numbers?

142,83,65,178,14,78.

i think 83 is the answer.

36/16=B THE ANSWER FOR EXPRESSION FOR .36 STUDENTS 36/16=20 BOYS THE ANSWER

"The median is the middle number. In this example, the numbers are already listed in numerical order, so I don't have to rewrite the list.**But there is no "middle" number, because there are an even number of numbers. In this case, the median is the mean (the usual average) of the middle two values**: (2 + 4) ÷ 2 = 6 ÷ 2 = 3"

14, 65, 78, 83, 142, 178

So you need to find the average (mean) between 78 and 83. How will you do that?

let x=total students

let y=total girls

let z=total boyz

z=x-y

z=36-16
