Question 117201: Can anyone tell me if I did this right.
x/10=9/30
Solve for x
Factors 9 and 30 have greatest common factor of 3. Reducing fraction.
It becomes x/10=3/10
Move these terms to the left - 3/10
It now becomes x/10-3/10=0
Solved linear equation x/10-3/10 equivalent to 0.1•x-0.3=0
It becomes 0=0
Solution x=3
If not can you show me where I went wrong.

You can put this solution on YOUR website!

x%2F10=9%2F30 Start with the given equation


x=%289%2F30%29%2A10 Multiply both sides by 10


x=90%2F30 Multiply


x=3 Simplify



So our answer is x=3


So you are correct, but I'm not sure where you got the step "0=0". As always, you can check this by plugging the solution back into the original equation

--------------------------------------
Check:

x%2F10=9%2F30 Start with the given equation


3%2F10=9%2F30 Plug in x=3


3%2F10=3%2F10 Reduce the right side. Since the two sides of the equation are equal, this verifies our answer.

Solved linear equation x/10-3/10 equivalent to 0.1•x-0.3=0
0.1x = 0.3
x = 0.3/0.1
x = 3
