Question

решите удобным способом.0,125*0.12*10*8= 0.96*7.22+2.78*0.96+2.4=

Answer 1

0,125*0.12*10*8=(0,125*8)* (0.12*10)=1*1,2=1,2                

0.96*7.22+2.78*0.96+2.4=    0.96*(7,22+2,78)+2,4=0,96*10+2,4=9,6+2,4=12

Answer 2

0,125*0.12*10*8=(0,125*8)*(0.12*10)=1*1.2=1.2

 

0.96*7.22+2.78*0.96+2.4=0.96*(7.22+2.78)+2.4=0.96*10+4=9.6+2.4=12
