0.6×2= 4.8÷0.6= 1.7+3= 4×9×0.25=
1.25×16= 9.6÷32= 2－0.09= 37 ＋47 ＝
119 －19 ＝ 14 －17 ＝ 1110 －38 ＝ 1/2 + 1/3 =
2/5 - 1/6 = 2/5 + 3/8 = 1 - 7/8 = 2/7 - 1/4 =
3/5 + 2/9 = 7/20 + 12/20= 1 - 5/11 - 6/11=
6 -（1/4 - 1/8）= 2/13 + 2/7 + 11/13 =
1/2+2/3 = 0.8+4.2 = 7/8 +3 = 2/5 －1/10 =
1.2 －1/5 = 5/13－2/39 = 1 －5/19 = 7.7 +3/10 =
12/5 －2 = 5 －9/16 = 1/100-1/1000= 1/100+1/1000=
0.6×2= 4.8÷0.6= 1.7+3= 4×9×0.25=

3/5 + 2/9 = 7/20 + 12/20= 1 - 5/11 - 6/11=
6 -（1/4 - 1/8）= 2/13 + 2/7 + 11/13 =
1/2+2/3 = 0.8+4.2 = 7/8 +3 = 2/5 －1/10 =
