Work: Calculate the value of equation abs((4/7)-(2/5))-abs((3/5)-(7/9))+abs((2/9)-(3/7)) .
Question type: Mathematical calculation
Solution:
abs((4/7)-(2/5))-abs((3/5)-(7/9))+abs((2/9)-(3/7))
=abs(0.571429-(2/5))-abs((3/5)-(7/9))+abs((2/9)-(3/7))
=abs(0.571429-0.4)-abs((3/5)-(7/9))+abs((2/9)-(3/7))
=abs0.171429-abs((3/5)-(7/9))+abs((2/9)-(3/7))
=abs0.171429-abs(0.6-(7/9))+abs((2/9)-(3/7))
=abs0.171429-abs(0.6-0.777778)+abs((2/9)-(3/7))
=abs0.171429-abs(-0.177778)+abs((2/9)-(3/7))
=abs0.171429-abs-0.177778+abs(0.222222-(3/7))
=abs0.171429-abs-0.177778+abs(0.222222-0.428571)
=abs0.171429-abs-0.177778+abs(-0.206349)
=0.171429-abs-0.177778+abs-0.206349
=0.171429-0.177778+abs-0.206349
=0.171429-0.177778+0.206349
=-0.006349+0.206349
=0.2
Answer:abs((4/7)-(2/5))-abs((3/5)-(7/9))+abs((2/9)-(3/7))=0.2
