1. 12b-(14b-5b)
=3b
2. (6a) / (2b)
=3
3. 10b-7b+b
=4b
4. 2a*3b
=6ab
=3b
2. (6a) / (2b)
=3
3. 10b-7b+b
=4b

1)
12b-(14b-5b) 12b-(14b-5b)
= 12b-9b = 12b-14b+5b
= 3b =3b
2)
6a/2b
= 3*(a/b)
= 3a/b
3)
10b-7b+b
= 3b+b
= 4b
4)
2a*3b
= 6ab
12b-(14b-5b) 12b-(14b-5b)
= 12b-9b = 12b-14b+5b
= 3b =3b
2)
6a/2b
= 3*(a/b)
= 3a/b
3)
10b-7b+b
= 3b+b
= 4b
4)
2a*3b
= 6ab

12b-(14b-5b) = 12b-14b+5b = 3b
6a/2b = 3(a/b) --> 即3又b分之a
10b-7b+b = 3b+b = 4b
2a*3b = 6ab
6a/2b = 3(a/b) --> 即3又b分之a
10b-7b+b = 3b+b = 4b
2a*3b = 6ab
