（1）2.64×1.7-2.64×0.7
=2.64×（1.7-0.7）
=2.64×1
=2.64
（2）31.5×1.07-3.15×0.7
=3.15×10.7-3.15×0.7
=3.15×（10.7-0.7）
=3.15×10
=31.5
（3）2.7×5.7-2.7+5.3×2.7
=2.7×(5.7-1+5.3）
=2.7×10
=27
（4）0.625÷0.125×0.8
=（0.625×0.8）×8÷（0.128×8）
=0.5×8÷1
=4

=27.7775
（7）52.5x2.9+5.45
=5.25x29+5.25+0.2
=5.25×（29+1）+0.2
=5.25×30+0.2
=157.5+0.3
=157.7
