In the box there are 10 items.
> Half of them are necklaces
> Two-fifths of the other are bracelets
The rest are rings, i.e. three-fifths.
First divide the total items by two to determine how many necklaces you have:
[tex]\frac{10}{2}=5[/tex]10/2=5
You have 5 necklaces, and the other 5 items are rings and bracelets.
2/5 are bracelets
3/5 are rings
Multiply them by the total of items and you get that:
[tex]5\cdot\frac{2}{5}=2[/tex]5*(2/5)=2
You have two bracelets
[tex]5\cdot\frac{3}{5}=3[/tex]5*(3/5)=3
You have three rings.
The jewlery box has 5 nacklaces, 2 bracelets and 3 rings.
