12.5*0.32*0.5
=(12.5x0.08)x(4x0.5)
=1x2
=2
3.2*2.4+32*0.76
=32x0.24+32x0.76
=32x(0.24+0.76)
=32x1
=32
=(12.5x0.08)x(4x0.5)
=1x2
=2
3.2*2.4+32*0.76
=32x0.24+32x0.76
=32x(0.24+0.76)
=32x1
=32

12.5*0.32*0.5 =(12.5*0.8)*(0.4*0.5)=10*0.2=2
3.2*2.4+32*0.76 =3.2*(2.4+0.76*10)=3.2*10=32
3.2*2.4+32*0.76 =3.2*(2.4+0.76*10)=3.2*10=32

12.5*0.32*0.5
=(12.5*0.8)*(0.4*0.5)
=10*0.2
=2
3.2*2.4+32*0.76
=3.2*(2.4+0.76*10)
=3.2*10
=32
=(12.5*0.8)*(0.4*0.5)
=10*0.2
=2
3.2*2.4+32*0.76
=3.2*(2.4+0.76*10)
=3.2*10
=32
