8.5%(3.6+6.8)÷1.3

8.5-(3.6+6.8)÷1.3 =8.5-(3.2+6.8+0.4)➗1.3 =8.5-10.4➗1.3 =8.5-8 =0.5

8.5-10.4/1.3=8.5-8=0.5

8.5-(3.6+6.8)÷1.3 =8.5-10.4÷1.3 =8.5-8 =0.5 没有简便方法,直接计算

除法那部分先提取公因式 (8.1-5.4)÷3.6 = (0.9 x 9 - 0.9 x 6)÷ (0.9 x 4)= 0.9 x (9 - 6) ÷ (0.9 x 4)= 0.9 x (9 - 6) ÷ 0.9 ÷ 4= (9 - 6) ÷ 4= 0.75 (8.1-5.4)÷3.6+85.7= 0.75 + 85.7= 85 + 0.7 + 0.75= 85 + (0.7 + 0.75)= 85 + 1.45= ...

(1)[8.5-(3.6+3.6)]÷2.6=[8.5-7.2]÷2.6=1.3÷2.6=0.5;(2)10.1×87=(10+0.1)×87=10×87+0.1×87=870+8.7=878.7;(3)1.4×[(7.5+38.4)÷0.9]=1.4×[45.9÷0.9]=1.4×51=71.4.

①1.4+3.6÷1.44×0.08 =1.4+2.5×0.08=1.4+0.2=1.6 ②0.83×6.8+11.7×0.68 =5.644+7.956=65.396=13.6 ③(3.12+0.9)÷[(1-0.4)÷0.1]=4.02÷[0.6÷0.1]=4.02÷6=0.67

7.8×6.4+3.6×1.3+3.6×6.5 =7.8×6.4+3.6×(6.5+1.3) =7.8x6.4+3.6x7.8 =7.8x(6.4+3.6) =7.8x10 =78

7.8*6.4 +3.6*1.3 +3.6*6.5 =7.8*6.4 +3.6*【1.3+6.5】 =7.8*【6.4+3.6】 =78 满意采纳

8.5÷5=1.77÷0.5=141÷4=0.256.3×101= 636.31.8÷0.9=20.9×6= ...3.7×5=24.50.64×99= 63.368×0.5=445÷0.5=90 4×0.25=13.6×...

7.8*6.4 +3.6*1.3 +3.6*6.5 =7.8*6.4 +3.6*【1.3+6.5】 =7.8*【6.4+3.6】 =78
