4/5-(1-1/6)
=4/5-(6/6-1/6)
=4/5-5/6
=24/30-25/30
=-1/30
=4/5-(6/6-1/6)
=4/5-5/6
=24/30-25/30
=-1/30

when you see parenthesis ()
you will have to calculate everything inside first
therefore:
step 1:
1 - 1/6
= 6/6 - 1/6
= 5/6
step 2:
put 5/6 back into the brackets
4/5 - (1 - 1/6)
= 4/5 - 5/6
then 通分母
= 24/30 - 25/6
= -1/30

(1-1/6) = 5/6
4/5 - 5/6
= 24/30 - 25/30
= - 1/30
Answer : - 1/30
4/5 - 5/6
= 24/30 - 25/30
= - 1/30
Answer : - 1/30

4/5 - (1-1/6)
= 4/5 - (6/6- 1/6)
= 4/5 - 5/6
= 24/30 - 25/ 30
= -1/30
= 4/5 - (6/6- 1/6)
= 4/5 - 5/6
= 24/30 - 25/ 30
= -1/30

answer= -1/30
steps:
4/5 - (1-1/6)
=4/5 - 1+1/6
=24/30 - 30/30 - 5/30 (通份)
=-1/30
steps:
4/5 - (1-1/6)
=4/5 - 1+1/6
=24/30 - 30/30 - 5/30 (通份)
=-1/30
2008-01-10 7:32 am
4/5 -(1- 1/6)
=4/5 -(6/6 -1/6)
=4/5-5/6
=24/30 - 25/30
= - 1/30
=4/5 -(6/6 -1/6)
=4/5-5/6
=24/30 - 25/30
= - 1/30
