\"Three people who work full-time are to work together on a project, but their total time on the project is to be equivalent to that of only one person working full-time. If one of the people is budgeted for one-half of his time and a second is budgeted for one-third her time, what portion of the third worker's time should be budgeted to this project?\":

Respuesta :

the equation to be used here is 1 full shift = 1/2 shift + 1/3 shift +x shift
equating everything to x you get x = 1 - 1/2 - 1/3 = 1/6

Answer:

Third person is budgeted for one-sixth of his time.

Step-by-step explanation:

Let x be the third worker's time that should be budgeted to this project.

It is given that three people who work full-time are to work together on a project.

First worker's time that should be budgeted = [tex]\frac{1}{2}[/tex]

Second worker's time that should be budgeted = [tex]\frac{1}{3}[/tex]

It is given that total time on the project is to be equivalent to that of only one person working full-time, i.e. 1.

[tex]\frac{1}{2}+\frac{1}{3}+x=1[/tex]

Isolate the variable x.

[tex]x=1-\frac{1}{2}-\frac{1}{3}[/tex]

Taking LCM, we get

[tex]x=\frac{6-3-2}{6}[/tex]

[tex]x=\frac{1}{6}[/tex]

The value of x is 1/6. Therefore the third person is budgeted for one-sixth of his time.
