Work: Calculate the value of equation 227.18×(0.86+0.91)-15.01×(0.5+1.9+0.91)-128.81×(0.88+0.91) .
Question type: Mathematical calculation
Solution:
227.18×(0.86+0.91)-15.01×(0.5+1.9+0.91)-128.81×(0.88+0.91)
=227.18×1.77-15.01×(0.5+1.9+0.91)-128.81×(0.88+0.91)
=227.18×1.77-15.01×3.31-128.81×(0.88+0.91)
=227.18×1.77-15.01×3.31-128.81×1.79
=402.1086-15.01×3.31-128.81×1.79
=402.1086-49.6831-128.81×1.79
=402.1086-49.6831-230.5699
=352.4255-230.5699
=121.8556
Answer:227.18×(0.86+0.91)-15.01×(0.5+1.9+0.91)-128.81×(0.88+0.91)=121.8556
