Given : Alex needs 80 cm of thread for a sewing project. The thread is on a spool with a circumference of 10 cm
To find : How many times must Alex unwind the spool to get the length of thread he needs
Solution:
thread is on a spool with a circumference of 10 cm
=> one time unwind will give length of thread = 10 cm
Thread length required by alex = 80 cm
Number of times alex unwind the spool = Thread length required / length in one unwind
= 80/10
= 8
Alex will unwind the spool 8 times to get the length of thread he needs
