Solve for x<br> (x/r)+(x/w)+(x/t)= 1
MissTica

<em>x</em>/<em>r</em> + <em>x</em>/<em>w</em> + <em>x</em>/<em>t</em> = 1

<em>x</em> (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>) = 1

<em>x</em> = 1 / (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>)

To make the solution a bit cleaner, multiply through the numerator and denominator by the LCM of each fraction's denominator, <em>rwt</em> :

<em>x</em> = 1 / (1/<em>r</em> + 1/<em>w</em> + 1/<em>t</em>) • <em>rwt</em> / <em>rwt</em>

<em>x</em> = <em>rwt</em> / (<em>rwt</em>/<em>r</em> + <em>rwt</em>/<em>w</em> + <em>rwt</em>/<em>t</em>)

<em>x</em> = <em>rwt</em> / (<em>wt</em> + <em>rt</em> + <em>rw</em>)

The formula for percent error is:

((Approximate value -  exact value) / exact value) x 100

1) 14-12 = 2

2/12 = 0.1666

0.166 x 100 = 16.7%  (Rounded to nearest tenth)

2) 231 - 215 = 16

16/215 = 0.74419

0.74419 x 100 = 7.4419% ( Round as needed)

3) 17.1 - 16.5 = 0.6

0.6/16.5 = 0.36364

0.36364 x 100 = 3.6364% (Round off as needed)

4)  1081 - 1150 = -69

-69/1150 = -0.06

-0.06 x 100 = -6% = 6% error
