Answer:
-11/35
Step-by-step explanation:
2/7-3/5
10/35-21/35
-11/35
Answer:
-11 / 35 is left
Step-by-step explanation:
Basically you just subtract the used length from the total length of the thread.
2/7 - 3/5
Make the denominators same before beginning!
Times 5 by both 2 and 7(top and bottom)
Times 7 by both 3 and 5(top and bottom)
(10-21)/35
= -11 / 35
