Question

An engineer was supposed to draw a line exactly 27/32 inch long. An error was made,and he drew the line 31/32 inch.how much longer was the line that the engineer drew?)

Answer 1

1/8 of an inch

Explanation:

Since the denominator is the same, we only need to subtract the numerator
31 - 27 = 8.

Now we have to simplify 8/32.

Divide both sides by 8, and you get 1/8
The engineer drew the line 1/8 of an inch longer than needed.
