Question

simplify using appropriate property 6/7*8/5*7/5*5/8​

Answer 1

Answer:

8/9×4/5+5/6−9/5×8/9

=8/9×4/5−9/5×8/9+5/6

Taking common terms, we get,

=8/9(4/5−9/5)+5/6

=8/9{(4−9)/5}+5/6

=8/9×−5/5+5/6

=8/9×(−1)+5/6

On further calculation, we get

=−8/9+5/6

Taking L.C.M. we get,

=(−16+15)/18

=−1/18.

Step-by-step explanation:

8/9×4/5+5/6−9/5×8/9

=8/9×4/5−9/5×8/9+5/6

Taking common terms, we get,

=8/9(4/5−9/5)+5/6

=8/9{(4−9)/5}+5/6

=8/9×−5/5+5/6

=8/9×(−1)+5/6

On further calculation, we get

=−8/9+5/6

Taking L.C.M. we get,

=(−16+15)/18

=−1/18.
