Work: Calculate the value of equation 12*50%-4+0.8-8*4.5%-5*7.5/75%-2.5*3.6% .
Question type: Mathematical calculation
Solution:
12*50%-4+0.8-8*4.5%-5*7.5/75%-2.5*3.6%
=12*0.5-4+0.8-8*4.5%-5*7.5/75%-2.5*3.6%
=12*0.5-4+0.8-8*0.045-5*7.5/75%-2.5*3.6%
=12*0.5-4+0.8-8*0.045-5*7.5/0.75-2.5*3.6%
=12*0.5-4+0.8-8*0.045-5*7.5/0.75-2.5*0.036
=6-4+0.8-8*0.045-5*7.5/0.75-2.5*0.036
=6-4+0.8-0.36-5*7.5/0.75-2.5*0.036
=6-4+0.8-0.36-37.5/0.75-2.5*0.036
=6-4+0.8-0.36-50-2.5*0.036
=6-4+0.8-0.36-50-0.09
=2+0.8-0.36-50-0.09
=2.8-0.36-50-0.09
=2.44-50-0.09
=-47.56-0.09
=-47.65
Answer:12*50%-4+0.8-8*4.5%-5*7.5/75%-2.5*3.6%=-47.65
