能简算的要简算,5.8x8/25+0.32x4.7-8除5 (4/5+5/3-1/15)x45 4.5x0.98
144除0.6-4.2x3

您好:

5.8x8/25+0.32x4.7-8除5
=5.8x0.32+0.32x4.7-1.6
=(5.8+4.7)x0.32-1.6
=10.5x0.32-1.6
=10x0.32+0.5x0.32-1.6
=3.2+0.16-1.6
=1.76

(4/5+5/3-1/15)x45
=4/5x45+5/3x45-1/15x45
=36+75-3
=108

4.5x0.98
=4.5x1-4.5x0.02
=4.5-0.09
=4.41

144除0.6-4.2x3
=240-12.6
=227.4
