A seamstress has 1/4 of a foot of thread. Then she uses 1/5 of a foot of thread to sew a hole. How much of the thread is left?
A. 9/20
B. 3/20
C. 1/20
D. 1/16
Yes, 1/20 is correct.
This is kind of a silly problem. 1/20 of a foot is about 1/2 an inch. 1/5 of a foot is about 2 1/2 inches.

To find out how much thread is left, you need to subtract the length of thread used from the initial length of thread.
The seamstress has 1/4 of a foot of thread. Then she uses 1/5 of a foot of thread to sew a hole.
To subtract fractions, you need a common denominator. The least common denominator for 4 and 5 is 20.
Converting both fractions to have a denominator of 20:
1/4 of a foot of thread is equivalent to 5/20, since 5 multiplied by 4 equals 20.
1/5 of a foot of thread is equivalent to 4/20 since 4 multiplied by 5 equals 20.
Now, subtracting the lengths of thread:
5/20 - 4/20 = 1/20.
So, the seamstress has 1/20 of a foot of thread left.
Therefore, the answer is C. 1/20.
