Work: Calculate the value of equation 400*2*4+2500*2*0.67/2*0.5*4+7.5*2*80/12*2 .
Question type: Mathematical calculation
Solution:
400*2*4+2500*2*0.67/2*0.5*4+7.5*2*80/12*2
=800*4+2500*2*0.67/2*0.5*4+7.5*2*80/12*2
=3200+2500*2*0.67/2*0.5*4+7.5*2*80/12*2
=3200+5000*0.67/2*0.5*4+7.5*2*80/12*2
=3200+3350/2*0.5*4+7.5*2*80/12*2
=3200+1675*0.5*4+7.5*2*80/12*2
=3200+837.5*4+7.5*2*80/12*2
=3200+3350+7.5*2*80/12*2
=3200+3350+15*80/12*2
=3200+3350+1200/12*2
=3200+3350+100*2
=3200+3350+200
=6550+200
=6750
Answer:400*2*4+2500*2*0.67/2*0.5*4+7.5*2*80/12*2=6750
