Question 97185
The fifth, fifteenth & fiftieth parts of a number  together make 43. Find the number.

x/5+x/15+x/50=43                          •This is the equation.

(150)x/5+(150)x/15+(150)x/50=43(150)      •Get the lcd which is 150.

30x+10x+3x=6450                           •Multiply the lcd to the numbers.

43x=6450                                  •Combine like terms.

x=150                                     •Divide the 43x by 43 to have the x
                                           and the 6450 by 43, then you'll have 
                                           the final answer.
