脱式计算,能简算的要简算. 0.25×0.125×32

解:0.25x32×0.125 =0.25x(4x8)×0.125 =(0.25x4)x(8×0.125) =1x1 =1

解:(0.125×0.8)×(0.25×0.4)=0.1×0.1=0.01

①0.125×0.25×8×4,=(0.125×8)×(0.25×4),=1×1,=1;②6.6×12+8×6.6,=(12+8)×6.6,=20×6.6,=132;③ 11 9 × 3 5 + 11 9 ÷ 2 5 = 11 9 × 3 5 + 11 9 × 5 2 ,=( 3 5 + 5 2 )× 11 9 ,=( 6 10 + 25 10 )× 11 9 ,= 31 10 × 11 9 ,= 341...
