Work: Calculate the value of equation 1.2×1.5×34+0.7×2.1×10+1.8×2.1×4+0.9×1.5×1 .
Question type: Mathematical calculation
Solution:
1.2×1.5×34+0.7×2.1×10+1.8×2.1×4+0.9×1.5×1
=1.8×34+0.7×2.1×10+1.8×2.1×4+0.9×1.5×1
=61.2+0.7×2.1×10+1.8×2.1×4+0.9×1.5×1
=61.2+1.47×10+1.8×2.1×4+0.9×1.5×1
=61.2+14.7+1.8×2.1×4+0.9×1.5×1
=61.2+14.7+3.78×4+0.9×1.5×1
=61.2+14.7+15.12+0.9×1.5×1
=61.2+14.7+15.12+1.35×1
=61.2+14.7+15.12+1.35
=75.9+15.12+1.35
=91.02+1.35
=92.37
Answer:1.2×1.5×34+0.7×2.1×10+1.8×2.1×4+0.9×1.5×1=92.37
