Question 335862: Hello, I have a question in regards to simplifying fractions.
Problem is 5/8x + 1/16x =11/16+x
I came up with x=88/80 and I was asked to simplify the answer, so because it is an improper fraction I turned it into a mixed number of 1 and(8/80), then I reduced it to 1 and(1/10). Can you please tell me if it is necessary to turn the problem into a mixed number?
Thanks in advance

Question 337211: multiply 3xyz2 over 6y4 by 2y over xz4
My assumption of the equation is written as (for it can be written in other ways also depends on the intent of the writer):
multiply 3xyz2 over 6y4 by 2y over xz4
{(3xyz)*(2)/6y4} x {(2y)/(xz4)}
Or
{(3xyz^2)/6y^4} x {(2y)/(xz^4)}
I take it is the later or here it is:
multiply 3xyz2 over 6y4 by 2y over xz4
{(3xyz^2)/6y^4} * {(2y)/(xz^4)}=
[{((3/6) * xyz^2)/y^4} * {((2/1) *y)/xz^4)}]=
Multiply numerator with numerator and denominator with denominator. consolidate numbers separate from letters. Simplify all numbers to lowest simple numbers. 2 is same as 2 over 1 or 2/1 and 3/6 is same as ½ divisable by 3.
[{(3/6) *(2/1)} * {(xyz^2*y)/(y^4*xz^4)}]=
(1/2)(2/1) * (xy^2z^2) / (xy^4z^4) =number divisible itself is one
2/2 * x/x*y^2/y^4*z^2/z^4 =
1*1*(1/y^2)*(1/z^2)=
1/(y^2*z^2)
