1)376200 / 495 = 760
2)760 - 193 = 567
3)48600 / 8 = 6075
4)206 * 567 = 116802
5)50 * 6075 = 303750
6)194815 + 116802 - 303750 = 7867

3 1/12+1/2 = 37/12 + 1/2 =(37 * 1 +1 * 6)/12 = 37/12 + 6/12 = 43/12 = 3 7/12
4 1/3 + 2/3 = 13/3 + 2/3 = 15/3 = 5
2 3/8 + 3 5/8 = 19/8 + 29/8 = 48/8 = 6
3 2/3 + 1 2/3 = 11/3 + 5/3 =16/3 = 5 1/3
