ANSWER
80 links
EXPLANATION
To find how many links would be in the necklace, we have to divide the total length of the necklace, 30 inches, by the length of each link, 3/8 inch,
[tex]30\div\frac{3}{8}[/tex]Use the KCF method:
• K,eep the first fraction
,• C,hange the division sign into a multiplication sign
,• F,lip the second fraction,
[tex]30\div\frac{3}{8}=30\times\frac{8}{3}[/tex]30 and 3 can be simplified - 30 is 3 times 10,
[tex]30\times\frac{8}{3}=10\times8=80[/tex]Hence, the necklace would have 80 links.
