Answer:
D. All of these are correct
Step-by-step explanation:
She needs four inches of ribbon and each spool has 24 inches, so we can write this equation like:
384/24 = s
where s is the number of spools.
If we divide 384 inches by the 24 inches each spool has she will get how many spools she needs.
Now having the equation: 384/24 = s, we can change it and it will mean the same.
384/24 = s is the same as 24s = 384; just sending the 24 to multiply on the other side.
And it is the same as 384/s = 24 just sending the s to the other side dividing.
So all of the answers are correct they are just in different orders.
