Question 312392
Remember that percentages are ratios comparing the part to the whole.

       {{{Part/whole =  2811/(2177+2811+1292+52) = 2811/6332}}}

Now change the fraction to a decimal by dividing:

2811 divided by 6332 = .4439

Change the decimal to a percent by multiplying by 100.

{{{.4439 * 100 = 44.39%}}}

Last step, round to the nearest tenth:
44.4%
