Question

直接写出得数．

7 9 + 7 12 =	3 5 + 9 11 =	17 18 - 1 4 =	6 7 - 5 6 =
1- 4 13 =	2 15 + 13 15 =	6.375-3 3 8 =	15-7 5 8 =

Answer 1

分析：根据整数、小数、分数加减法的计算方法进行计算即可得到答案．

解答：解：

7 9 + 7 12 =1 13 36	3 5 + 9 11 =1 23 55	17 18 - 1 4 = 25 36	6 7 - 5 6 = 1 42
1- 4 13 = 9 13	2 15 + 13 15 =1	6.375-3 3 8 =3	15-7 5 8 =7 3 8

点评：此题主要考查的是分数加减法计算方法的应用．
