Homework Help: math

Posted by felicia on Wednesday, May 23, 2007 at 9:06pm.

i need help with this question can u please show me how to figure this out and show me how you figured out the problem. the question is 1/3 pnut butter sandwiches 1/6 cheese and 9 ham how many total?

i assume you mean how many sandwhiches total? in that case just add the fractions, if you dont have a calculator then start by finding the GCD or greatest common denominator, then add! :)

let x = total sandwitches

1/3 x + 1/6 x + 9 = x
Or 2/6x +1/6x + 9 = x
combine like terms

3/6x + 9 = x

or
1/2x +9 =x


multiply both sides by 2
so

x +18 = 2x

Now adda -x to both sides
18 = x
