1) 117/20 - 352/100 + 4/5 = (585 - 352 + 80) / 100 = 313/100 = 3.13 2) 153/25 + 281/100 - 7/4 = (612 +281 - 175) / 100 = 718/100 = 7.18 3) 97/10 + 592/100 - 69/20 = (970 + 592 - 345) / 100 = 1217/100 = 12.17 4) 417/10 - 43/5 + 9/4 = (834 - 172 + 45) / 20 = 707/20 = 35.35 5) 3663/100 + 39/4 - 69/10 = (3663 + 975 - 690) / 100 = 3948/100 = 39.48 6) 5875/100 - 219/10 + 108/5 = (5875 - 2190 + 2160) / 100 = 5845/100 = 58.45
