300÷125÷8
=300÷(125×8)
=300÷1000
=0.3
396-96-172-28
=(396-96)-(172+28)
= 300-200
= 100
125*24
= 125*8*3
= 1000
0.25×1.25×0.67×32
=0.25×1.25×0.67×4×8
=(0.25×4)×(0.125×8)×0.67
=1×1×0.67
=0.67
0.99×0.81＋0.11×9×0.19
=0.99×0.81+0.99×0.19
=0.99×(0.81+0.19)
=0.99×1
=0.99
33.41÷4-3.41×0.25
=33.41×1/4-3.41×1/4
=(33.41-3.41)×1/4
=30×1/4
=7.5
(5.23＋5.23＋5.23＋5.23) ×25
=5.23×4×25
=5.23×100
=523
(79+92+121)+108
= (79+121)+(92+108)
=200+200
=400
(37+56+63)+44
= (37+63)+(56+44)
=100+100
=200
=300÷(125×8)
=300÷1000
=0.3
396-96-172-28
