3.6×0.75×1.2）÷（1.5×24×0.18）
=（1.8×2×0.75×12÷10）÷（1.5×24×0.18）
=（1.8×1.5×12÷10）÷（1.5×24×0.18）
=0.5
26.44÷0.4+13.22+1.8
=13.22×2÷4×10+13.22+1.8
=13.22×5+13.22+1.8
=13.22×6+1.8
=79.32+1.8=81.12
26.39×36+26.39×83-263.9×1.9
=26.39×36+26.39×83-26.39×19
=26.39×（36+83-19）
=26.39×100
=2639
2.25×0.16+264×0.0225+52×2.25+0.225×2
=2.25×0.16+2.64×2.25+52×2.25+2.25×0.2
=2.25×（0.16+2.64+52+0.2）
=2.25×55
=2.25×50+2.25×5
=112.5+1.125
=123.75
