\(=1275:96+46-\dfrac{68}{67}\times152=\dfrac{425}{32}+46-\dfrac{10336}{67}=\dfrac{1897}{32}-\dfrac{10336}{67}=-94,98740672.\)

Hướng dẫn giải:
a) 93 + 39 + 7 = (93 + 7) + 39 = 100 + 39 = 139.
89 + 85 + 11 = (89 + 11) + 85 = 100 + 85 = 185
184 + 66 + 16 = (184 + 16) + 66 = 200 + 66 = 266
b) 23 + 52 + 47 + 98 = (23 + 47) + (52 + 98) = 70 + 150 = 220
16 + 490 + 84 + 10 = (16 + 84) + (490 + 10) = 100 + 500 = 600
