Answer:
9 3/4 = 975%
Step-by-step explanation:
Let's take an example to illustrate this case:
<span>positive fraction = 2/7
</span>
<span>negative fraction = - 3/5
Now we need to subtract </span><span>- 3/5 from 2/7
Right?
2/7 - (-3/5) = 2/7 + 3/5
here we need to unify the denominators as follows:
the lowest common factor between 7 and 5 is 35
2/7 = 10/35
3/5 = 21/35
Now back to </span><span>2/7 + 3/5:
</span><span><span>2/7 + 3/5 = 10/35 + 21/35 = (10+21)/35 = 31/35
That's it
Hope that helps you</span>

Answer:
r = 
Step-by-step explanation:
The common ratio r of a geometric sequence is
r =
=
=
= ......
r =
=
= 
(16a^6b^8-24ab^9)/4a^6b^8
(4-6ab^1)/a^6b
Hope this helps :)
