Okay! In order to get the answer you'd first have to add the fractions. To do that you have to get a common denominator of 37/50 and 3/100. In order to get the common denominator you multiply the bottom and the top of 37/50 by 2:
[37 x 2] = 74
==
[50 x 2] = 100
Then you add the two fractions together, but add only the numerators and keep the denominator. So:
[74 + 3] = 77 ⇒ 77/100.
Then add the whole numbers:
[517 + 312] = 829.
The answer is 829 77/100.
