25×12.5
25×12.5
25×12.5
(0.25 x 4) x(12.5 x 4) =1 x 50 =50
16×0.25×12.5
=（4×¼）×（4×12.5）
=1×50
=50
16×0.25×12.5
=4×4×0.25×12.5
=(4×.0.25)×(4×12.5)
=1×20
=20
(4x 0.25) x(12.5 x 4) =50
(4×0.25)×4×12.5=5 0
=(4*4)*0.25*(5*2.5)
=(4*0.25)*(4*2.5)*5
=1*10*5
=50
16×0.25×12.5
=（4×4）×0.25×12.5
=0.25×4×12.5×4
=1×50
=50
16×0.25×12.5
=（2×8）×0.25×12.5
=（2×0.25）×（8×12.5）
=0.5×100
=50
16×0.25×12.5
=（4x4)x0.25×12.5
=(4x0.25)x(4x12.5)
=1x50
=50
2×0.25×（8×12.5）
16×0.25×12=4×0.25×4×12.5=1×50=50
16×0.25×12.5
= 4×4×0.25×12.5
=（4×0.25）×（4×12.5）
= 1×5
=5
16×0.25×12.5
=16×1/4×12.5
=4×12.5
=50
把16分成4×4，就等于4×0.25×4×12.5
16×0.25×12.5
=4×4×0.25×12.5
=4×(4×0.25)×12.5
=4×1×12.5
=50
