Answer:

2/10 or 1/5 if you want it simplified

Step-by-step explanation:

9/10 is basically 9 and 7/10 is 7 so 9 - 7 is 2 and we need to add the /10 back so it's 2/10 or 1/5

Step-by-step explanation:

want to draw=7/10

mistakely draw=9/10

here,

9/10

- 7/10

2/0

therefore, the engineer draw the line 2/0 longer than he need
