25分之41除以13分之11除以百分之164简便计算（要过程）

41/25 ÷ 11/13 ÷ 164%
= 41/25 × 13/11 ÷ 41/25
= (41/25 ÷ 41/25) × 13/11
= 13/11
3/4×25/8 + 5.875×75% + 0.75
= 0.75×25/8 + 5.875×0.75 + 0.75
= 0.75 × (25/8+5.875+1)
= 0.75 × (3.125+5.875+1)
= 0.75 × 10
= 7.5
(8.4-2.4×5/2) ÷ 8
= (1.2×7 - 1.2×5) ÷ 8
= 1.2 × (7-5) ÷ 8
= 1.2 × 2 ÷ 8
= 1.2 ÷ 4
= 0.3
(6.35×65%+3.66×13/20)÷10%
= (6.35×65%+3.66×65%)÷10%
= (6.35+3.66)×65%÷10%
= 10.01 × (65%÷10%)
= 10.01 × 6.5
= 10 × 6.5 + 0.1×6.5
= 65+0.65
= 65.65
