1/8 of the original sum still remains.
Step-by-step explanation:
If you spend 3/4 of what you have, you have 1/4 left.
Now you spend 1/2 of that 1/4, so basically divide 1/4 by 2. When dividing fractions you can multiply the fraction by the reciprocal of the other fraction.
÷
=
*
= 1/8
So I think 1/8 of the original sum still remains.

Step-by-step explanation:
so, Katherine can do 0.1 of the job per hour. (if she needs 10 hours for the job, each hour she can do the whole divided by the time, so 1/10, which is 0.1)
