0.36*13+1.3*6.4的简便算法,列式.

0.36*13+1.3*6.4的简便算法,列式.
0.36*13+1.3*6.4的简便算法,列式.

0.36*13+1.3*6.4的简便算法,列式.
0.36*13+1.3*6.4
=3.6*1.3+1.3*6.4
=1.3*(3.6+6.4)
=1.3*10
=13

0.36*13+1.3*6.4
=3.6×1.3+1.3×6.4
=1.3×(3.6+6.4)
=1.3×10
=13

0.36*13+1.3*6.4
=1.3×3.6+1.3×6.4
=1.3×﹙3.6+6.4)
=13

=300/301 2、【13/8-(5/8+5/7)】×3/4 =(13/8-5/8-5/7)×3/4 =(1-5/7)×3/4 =2/7×3/4 =3/14 1、原式的分子分母
