Work: Calculate the value of equation 155×(2.55+3.75+3.35+2.95)+1/2×52.7×1.95×2.6+1/2×52.7×11×2.75 .
Question type: Mathematical calculation
Solution:
155×(2.55+3.75+3.35+2.95)+1/2×52.7×1.95×2.6+1/2×52.7×11×2.75
=155×12.6+1/2×52.7×1.95×2.6+1/2×52.7×11×2.75
=1953+1/2×52.7×1.95×2.6+1/2×52.7×11×2.75
=1953+0.5×52.7×1.95×2.6+1/2×52.7×11×2.75
=1953+26.35×1.95×2.6+1/2×52.7×11×2.75
=1953+51.3825×2.6+1/2×52.7×11×2.75
=1953+133.5945+1/2×52.7×11×2.75
=1953+133.5945+0.5×52.7×11×2.75
=1953+133.5945+26.35×11×2.75
=1953+133.5945+289.85×2.75
=1953+133.5945+797.0875
=2086.5945+797.0875
=2883.682
Answer:155×(2.55+3.75+3.35+2.95)+1/2×52.7×1.95×2.6+1/2×52.7×11×2.75=2883.682
