Answer:
There are <u>20 beads</u> on the necklace.
Step-by-step explanation:
Given:
A beaded necklace is 2.5 feet long. Each bead is .25 inches wide & each pair of beads is separated by 1.25 inches of chain.
Now, to find the number of beads on the necklace.
The length of necklace = 2.5 feet.
So, we convert feet into inches by using conversion factor:
<em>1 foot = 12 inches.</em>
<em>2.5 feet = 12 × 2.5 inches.</em>
<em>2.5 feet = 30 inches.</em>
<u>Thus, the length of necklace is 30 inches.</u>
Let the number of beads be
The width of each bead = 0.25 inches.
The each pair of beads is separated by 1.25 inches.
Now, we put an equation to get the number of beads:
<em>Dividing both sides by 1.50 we get:</em>
<u><em>The number of beads = 20.</em></u>
Therefore, there are 20 beads on the necklace.
