Work: Calculate the value of equation ((19.8×7.7+20×2.1+25×(-56.6))/(20.68×(6.3+7.7))) .
Question type: Mathematical calculation
Solution:
((19.8×7.7+20×2.1+25×(-56.6))/(20.68×(6.3+7.7)))
=((19.8×7.7+20×2.1+25×(-56.6))/(20.68×(6.3+7.7)))
=((-1220.54)/(20.68×(6.3+7.7)))
=(-1220.54/(20.68×14))
=(-1220.54/289.52)
=-4.215736
Answer:((19.8×7.7+20×2.1+25×(-56.6))/(20.68×(6.3+7.7)))=-4.215736
