Question

（2014•泉州模拟）

用递等式计算 102×22-1428÷14

4.7-0.7×1.5-0.95

8.75×3.6+12.5×0.36

(1)/(3)÷[（(2)/(3)+(1)/(5)）×(1)/(13)]

Answer 1

（1）102×22-1428÷14
=2244-102
=2142；

（2）4.7-0.7×1.5-0.95
=4.7-1.05-0.95
=4.7-（1.05+0.95）
=4.7-2
=2.7；

（3）8.75×3.6+12.5×0.36
=8.75×3.6+1.25×3.6
=（8.75+1.25）×3.6
=10×3.6
=36；

（4）(1)/(3)÷[（(2)/(3)+(1)/(5)）×(1)/(13)]
=(1)/(3)÷[(13)/(15)×(1)/(13)]
=(1)/(3)÷(1)/(15)
=5．
