Work: Calculate the value of equation (23×6.28×64.19+15×75.31)/(((23×9.6+22×2.5+19.1×2.4+22×0.5)/(9.6+2.5+2.4+0.5))×(8.72+6.28)+20) .
Question type: Mathematical calculation
Solution:
(23×6.28×64.19+15×75.31)/(((23×9.6+22×2.5+19.1×2.4+22×0.5)/(9.6+2.5+2.4+0.5))×(8.72+6.28)+20)
=10401.2536/(((23×9.6+22×2.5+19.1×2.4+22×0.5)/(9.6+2.5+2.4+0.5))×(8.72+6.28)+20)
=10401.2536/((332.64/(9.6+2.5+2.4+0.5))×(8.72+6.28)+20)
=10401.2536/((332.64/15)×(8.72+6.28)+20)
=10401.2536/(22.176×(8.72+6.28)+20)
=10401.2536/(22.176×15+20)
=10401.2536/352.64
=29.495388
Answer:(23×6.28×64.19+15×75.31)/(((23×9.6+22×2.5+19.1×2.4+22×0.5)/(9.6+2.5+2.4+0.5))×(8.72+6.28)+20)=29.495388
