Work: Calculate the value of equation (2/3)/(4/31)-4/9+3/11-(1+2/3)/3-5/(2+1/5) .
Question type: Mathematical calculation
Solution:
(2/3)/(4/31)-4/9+3/11-(1+2/3)/3-5/(2+1/5)
=0.666667/(4/31)-4/9+3/11-(1+2/3)/3-5/(2+1/5)
=0.666667/0.129032-4/9+3/11-(1+2/3)/3-5/(2+1/5)
=0.666667/0.129032-4/9+3/11-1.666667/3-5/(2+1/5)
=0.666667/0.129032-4/9+3/11-1.666667/3-5/2.2
=5.16668-4/9+3/11-1.666667/3-5/2.2
=5.16668-0.444444+3/11-1.666667/3-5/2.2
=5.16668-0.444444+0.272727-1.666667/3-5/2.2
=5.16668-0.444444+0.272727-0.555556-5/2.2
=5.16668-0.444444+0.272727-0.555556-2.272727
=4.722236+0.272727-0.555556-2.272727
=4.994963-0.555556-2.272727
=4.439407-2.272727
=2.16668
Answer:(2/3)/(4/31)-4/9+3/11-(1+2/3)/3-5/(2+1/5)=2.16668
