Question

计算：
（0.5+0.25+0.125）÷（0.5×0.25×0.125）×((7)/(18)×(9)/(2)+(1)/(6))/(13(1)/(3)−(15)/(4)×(16)/(5))．

Answer 1

（0.5+0.25+0.125）÷（0.5×0.25×0.125）×((7)/(18)×(9)/(2)+(1)/(6))/(13(1)/(3)−(15)/(4)×(16)/(5))
（(1)/(2)+(1)/(4)+(1)/(8)）÷（(1)/(2)×(1)/(4)×(1)/(8)）×((7)/(4)+(1)/(6))/(13(1)/(3)−12)
=（(1)/(2)+(1)/(4)+(1)/(8)）×2×4×8×((7)/(4)+(1)/(6))/(13(1)/(3)−12)

=（4+2+1）×2×4×((21)/(12)+(2)/(12))/(1(1)/(3))
=7×2×4×(23)/(4×4)
=7×(23)/(2)
=80(1)/(2)．
