Final answer:
To find the amount of thread on each of Lucy's 7 spools, divide the total inches of thread, 1,136.93, by 7, giving approximately 162.4 inches of thread per spool, rounded to the nearest tenth.
Step-by-step explanation:
Lucy bought 7 spools of purple thread and obtained a total of 1,136.93 inches of thread. To find out how many inches of thread were on each spool, we need to divide the total number of inches by the number of spools.
To perform this calculation:
Divide 1,136.93 by 7.
The calculation is 1,136.93 ÷ 7 = 162.4185714.
Rounded to the nearest tenth, this gives us approximately 162.4 inches of thread per spool.
Therefore, each spool had about 162.4 inches of thread when rounded to the nearest tenth.
