分数简便计算题60道
分数简便计算题60道一、同分母分数加减法1. (3)/(7)+(2)/(7)同分母分数相加,分母不变,分子相加就好啦。
3加2等于5,所以答案就是(5)/(7)。
2. (5)/(9)-(2)/(9)分母是9不变,分子5减2等于3,那结果就是(3)/(9),约分一下就是(1)/(3)。
3. (4)/(11)+(5)/(11)+(2)/(11)分母都是11,把分子4、5、2加起来,4 + 5+2 = 11,所以答案是(11)/(11)=1。
4. (7)/(13)-(3)/(13)-(1)/(13)分母13不变,分子7-3 - 1=3,答案就是(3)/(13)。
5. (2)/(15)+(8)/(15)-(4)/(15)分母15不变,分子2 + 8-4 = 6,结果是(6)/(15),约分后为(2)/(5)。
6. (9)/(17)+(3)/(17)+(5)/(17)分母17不动,分子相加9+3 + 5 = 17,答案就是1。
7. (11)/(21)-(5)/(21)+(8)/(21)分母21不变,分子11-5+8 = 14,结果是(14)/(21),约分后为(2)/(3)。
8. (13)/(23)-(7)/(23)-(3)/(23)分母23不变,分子13 - 7-3 = 3,答案为(3)/(23)。
9. (1)/(19)+(10)/(19)+(8)/(19)分母19不变,分子相加1+10 + 8 = 19,结果是1。
10. (15)/(29)-(9)/(29)-(4)/(29)分母29不变,分子15-9 - 4 = 2,答案是(2)/(29)。
11. (3)/(31)+(16)/(31)+(12)/(31)分母31不变,分子相加3+16+12 = 31,答案为1。
12. (17)/(35)-(8)/(35)+(10)/(35)分母35不变,分子17 - 8+10 = 19,结果是(19)/(35)。
13. (21)/(43)-(13)/(43)-(5)/(43)分母43不变,分子21-13 - 5 = 3,答案为(3)/(43)。
