There are 24 inches of ribbon in each spool. Margaret needs 384 inches of ribbon. Which equation can Margaret use to find the number of spools, s, she needs?

Respuesta :

Answer: There are 16 spools she needs

Step-by-step explanation:

Since we have given that

Length of ribbons in each spool = 24 inches

Length of ribbons Margaret needed = 384 inches

According to question,

We need to find the number of spools say s,

[tex]s=\frac{\text{Total length of ribbon}}{\text{Length of ribbon in each spool}}[/tex]

[tex]s=\frac{384}{24}=16[/tex]

Hence, there are 16 spools she needs.

Answer:

[tex]x=\frac{inches \ of \ ribbon}{inches \ per \ spool}[/tex]

Step-by-step explanation:

Givens:

  • There are 24 inches of ribbon per spool.
  • Margaret needs 384 inches of ribbon.

If we think about it, we realize that we need to divide all 384 inches of ribbon by 24 inches, which represents each spool. This  division is what is going to give us the number of spools.

Another way to solve this, it's using the rule of three, if one spool is 24 inches, how many spools would get form 384 inches:

[tex]x=384\frac{1}{24}=16[/tex]

So, the number of spools would be 16.

If you want only the expression it would be

[tex]x=\frac{inches \ of \ ribbon}{inches \ per \ spool}[/tex]
