Question

计算：((16(8)/(247)×2.375+12(4)/(285)×4.75)×19.98)/(6.66×(48×2−(167)/(195)))=______．

Answer 1

((16(8)/(247)×2.375+12(4)/(285)×4.75)×19.98)/(6.66×(48×2−(167)/(195)))
=([(16+(8)/(247))×(19)/(8)+(12+(4)/(285))×(19)/(4)]×19.98)/(6.66×(96−(167)/(195)))，
=((16×(19)/(8)+(8)/(247)×(19)/(8)+12×(19)/(4)+(4)/(285)×(19)/(4))×3)/(95(28)/(195))，
=((38+(1)/(13)+57+(1)/(15))×3)/(95(28)/(195))，
=((95+(28)/(195))×3)/(95(28)/(195))，
=3．
故答案为：3．
