Answer 1

1) 4 + 12/35 + 7 + 11/14 = 4 + 0.342857 + 7 + 0.785714 = 11 + 0.342857 + 0.785714 = 11 + 1.128571 = 12.128571

2) 9 + 8/15 + 7 + 11/12 = 9 + 0.533333 + 7 + 0.916667 = 16 + 0.533333 + 0.916667 = 16 + 1.45 = 17.45

3) 14 + 7/18 - 11 + 11/12 = 14 + 0.388889 - 11 + 0.916667 = 14 + 0.388889 - 11 + 0.916667 = 3 + 0.388889 + 0.916667 = 3 + 1.305556 = 4.305556

4) 4 + 3/16 - 3 + 7/24 = 4 + 0.1875 - 3 + 0.291667 = 4 + 0.1875 - 3 + 0.291667 = 1 + 0.1875 + 0.291667 = 1 + 0.479167 = 1.479167

Итак, результаты вычислений: 1) 12.128571 2) 17.45 3) 4.305556 4) 1.479167
