2.95x47.8+6.21x52.2+0.478x326
=2.95x47.8+6.21x52.2+47.8x3.26
=2.95x47.8+47.8x3.26+6.21x52.2
=47.8x(3.26+2.95)+6.21x52.2
=47.8x6.21+6.21x52.2
=(47.8+52.2)x6.21
=100x6.21
=621
=2.95x47.8+6.21x52.2+47.8x3.26
=2.95x47.8+47.8x3.26+6.21x52.2
=47.8x(3.26+2.95)+6.21x52.2
=47.8x6.21+6.21x52.2
=(47.8+52.2)x6.21
=100x6.21
