Work: Calculate the value of equation 3.9×15+3.6+3.3×6+2.2×18+(3.9×17+3.6+3.3×4+2.2×18)×9 .
Question type: Mathematical calculation
Solution:
3.9×15+3.6+3.3×6+2.2×18+(3.9×17+3.6+3.3×4+2.2×18)×9
=3.9×15+3.6+3.3×6+2.2×18+122.7×9
=58.5+3.6+3.3×6+2.2×18+122.7×9
=58.5+3.6+19.8+2.2×18+122.7×9
=58.5+3.6+19.8+39.6+122.7×9
=58.5+3.6+19.8+39.6+1104.3
=62.1+19.8+39.6+1104.3
=81.9+39.6+1104.3
=121.5+1104.3
=1225.8
Answer:3.9×15+3.6+3.3×6+2.2×18+(3.9×17+3.6+3.3×4+2.2×18)×9=1225.8
