Answer:
A) 6 friends
B) 12 blue beads and 7 red beads
Step-by-step explanation:
<em>Step 1: Find the total number of beads</em>
Blue beads + red beads = Total beads
72 + 42 = 114
<em>Step 2: Find the ratio of blue beads to red beads</em>
Blue/red = 72/42 = 12/7
<em>Step 3: Find the total number of beads in each necklace</em>
Add the ratio found in step 2
12 + 7 = 19 beads in each necklace
<em>Step 4: Find the number of necklaces</em>
Total beads/beads in each necklace
114/19 = 6
There will be 6 identical necklaces.
A) 6 friends will receive a necklace
B) Each friend will receive 12 blue beads and 7 red beads on each necklace.
