\(17.8°\)

 

The degree  rounded to the nearest whole number is \(18\)

 

To find the minute divide the decimal portion of the degree by \(60\)

 

\(\frac{0.8}{60}\)

 

\(\frac{8}{600}\)

 

\(\frac{1}{75}\)

 

0.0133333333333333...

 

The minute rounded to the nearest whole number is \(0\)

 

To find the second divide the decimal portion of the degree by 60

 

\(\frac{0.0133333333333333...}{60}\)

 

\(\frac{\frac{2}{15}}{60}\)

 

\(\frac{2}{15}\times\frac{1}{60}\)

 

\(\frac{2}{900}\)

 

\(\frac{1}{450}\)

 

\(0.0022222222222222...\)

 

The second rounded to the nearest whole number is \(0\)

 

Putting the degree minute and second numbers togother and you get \(18°0"0'\)

There are 60 minutes in every degree......so.....

 

In  .8   of a degree there are   .8 x 60  = 48 minutes

 

So     17.8°    =   17 degrees, 48 minutes

 

 

cool cool cool
