Question

5. A jewelry box has 10items. Of those, half arenecklaces. Two-fifths of theothers are bracelets. Therest are rings. How manyrings are there?

Answer 1

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:

`(10)/(2)=5`

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:

`5\cdot(2)/(5)=2`

5*(2/5)=2

You have two bracelets

`5\cdot(3)/(5)=3`

5*(3/5)=3

You have three rings.

The jewlery box has 5 nacklaces, 2 bracelets and 3 rings.
