Question

How do I simplify this problem: 10x*12*25y/2z*30x*20y.... do understand... please help!!!

Answer 1

I assume it is a fraction with 3 terms as the numerator and 3 as the denominator?

Answer 2

You can either simplify the numerator by multiply all the terms and getting 3000xy
doing the same for the denominator 1200xyz
and then simplifying 5/(2z)
the xy on the numerator cancel with the xy in the denominator

Answer 3

or you can cancel terms and then simplify but you get the same answer 5/(2z)

Answer 4

ok thats what I had but my teacher said i was wrong

Answer 5

what did the teacher say was the correct answer?

Answer 6

he didnt he just told me to re do it.

Answer 7

Is it written as a fraction or exactly as above?

Answer 8

so if you write this fraction hence :

10x*12*25y
---------- = so here you can seeing what you can simplify
2z*30x*20y

- so if you simplify 10x with 30x you gat that in denominator will remain3 because 3 multiplied with 10x equal 30x
- i think that with 12 you want writing one z again and hence you can simplify 12z with 2z what resulte to you 6 in nominator because 6 multiplied with 2z equal 12z
- 25y you can simplify with 5y and hence in nominator will remain 5 and in denominator 4 because 5 multiplied with 5y equal 25y and because 5y multiplied with 4 equal 20y

so hence will remain to you from this fraction

10x*12z*25y 6*5 30 5
----------- = ---- = --- = ---
2z*30x*20y 3*4 12 2

- hope so much that you have understood it all clearly

Answer 9

yrs i understand clearly. i did it the long way and came up with the same answer. but thanks you again.
