一、口算。
120 - 80 =
3.6 - 2.7 =
130 + 70 =
25×30 =
42 + 58 =
36×6 =
86 - 66 =
1.4 + 4.1 =
20×40 =
47×20 =
5.5 - 4.5 =
39 + 37 =
1.6 + 2.9 =
270÷9 =
42×7 =
350×2 =
872÷8 =
5.8 - 3.6 =
13×20 =
3.8 - 2.9 =
24×30 =
5×700 =
2.5 + 7.5 =
60÷4 =
$\frac{1}{6}$ + $\frac{4}{6}$ =
$\frac{7}{8}$ - $\frac{4}{8}$ =
$\frac{11}{15}$ + $\frac{4}{15}$ =
$\frac{9}{10}$ - $\frac{2}{10}$ =
$\frac{2}{7}$ + $\frac{3}{7}$ =
1 - $\frac{17}{18}$ =

答案： 40 0.9 200
750 100 216
20 5.5 800
940 1 76
4.5 30 294
700 109 2.2
260 0.9 720
3500 10 15
$\frac{5}{6}$ $\frac{3}{8}$ 1
$\frac{7}{10}$ $\frac{5}{7}$ $\frac{1}{18}$

二、计算下面各题。
336÷7 + 502
(152 - 74)×43
699 - 15×32

答案： 550 3354 219
