到百度去搜,可多了

1、 原式=(300-15/16)x1/15+(140-7/8)x1/7+(60-3/4)x1/3=20-1/16+20-1/8+20-1/4=60-(1/16+1/8+1/4)=60-7/16(通分)=59又9/16 2、1+1/2+1/3+1/4)×(1/2+1/3+1/4+1/5)-(1+1/2+1/3+1/4+1/5)×(1/2+1/3+1/4)=? 解法:令1/2+1/3+1/4=a, 1/5...

可以请您具体描述一下吗,是只要是乘法简便运算题就可以了吗,还是有什么具体要求,这样才能更好的帮助您

4/9×3= 5÷1/3 = 1/2÷1/3 = 2/7×3/9 ÷2/7 = 21/25÷42= 4/5×3/4 = 8.7×0.2= 4×0.25= 1/7×14= 2/3÷5/6= 1.25×8= 3/5÷5/8= 6/7×3/2= 6×8.8= 4/11÷4= 4/9×3/8= 5/3÷5= 0÷8/3= 4/7 -2/3= 2/7×2 = 41/12×4= 4÷3/16= 12÷9/4 = 75/8 ÷5= 12×16/9 = 2/3...

1.3/7 × 49/9 - 4/3 2.8/9 × 15/36 + 1/27 3.12× 5/6 – 2/9 ×3 4.8× 5/4 + 1/4 5.6÷ 3/8 – 3/8 ÷6 6.4/7 × 5/9 + 3/7 × 5/9 7.5/2 -( 3/2 + 4/5 ) 8.7/8 + ( 1/8 + 1/9 ) 9.9 × 5/6 + 5/6 10.3/4 × 8/9 - 1/3

先给钱再发过去

分数乘法计算题: 4/9×3= 2/7×3/9 = 4/5×3/4 = 8.7×0.2= 4×0.25= 1/7×14= 1.25×8= 6/7×3/2= 4/9×3/8= 2/7×2 = 41/12×4= 12×16/9 = 2/3×3= 4/5×5/8 =
