16.8×1.3+4.2×4.2+9.6×4.2
=16.8÷4×1.3×+4.2×4.2+9.6×4.2
=4.2×5.2+4.2×4.2+9.6×4.2
=4.2×(5.2+4.2+9.6)
=4.2×19
=4.2×(20-1)
=4.2×20-4.2×1
=84-4.2
=84-4-0.2
=80-0.2
=79.8
=16.8÷4×1.3×+4.2×4.2+9.6×4.2
=4.2×5.2+4.2×4.2+9.6×4.2
=4.2×(5.2+4.2+9.6)
=4.2×19
=4.2×(20-1)
=4.2×20-4.2×1
=84-4.2
=84-4-0.2
=80-0.2
=79.8
