Answer

45% of the beads are round, and 55% are rectangular.

Solution

To determine the percentages of round and rectangular beads on the necklace: 1. **Total beads on the necklace:** 100 2. **Number of round beads:** 45 3. **Number of rectangular beads:** \[ 100 \text{ (total beads)} - 45 \text{ (round beads)} = 55 \text{ rectangular beads} \] 4. **Calculating the percentages:** - **Percentage of round beads:** \[ \left( \frac{45}{100} \right) \times 100\% = 45\% \] - **Percentage of rectangular beads:** \[ \left( \frac{55}{100} \right) \times 100\% = 55\% \] **Summary:** - **45%** of the beads are round. - **55%** of the beads are rectangular.

Beyond the Answer

To find the percentage of round beads, you take the number of round beads (45) and divide it by the total number of beads (100), then multiply by 100. This gives you 45%. For the rectangular beads, you subtract the round beads from the total, which gives you 55 rectangular beads. Then, divide that by the total number of beads (100) and multiply by 100, resulting in 55%. So, 45% of the beads are round, and 55% are rectangular! Would you believe that jewelry-making has roots dating back thousands of years? Ancient Egyptians adorned themselves with beads for spiritual purposes and status symbols. Today, beads have evolved into endless designs and materials, offering the perfect personal touch to any necklace! When crafting your own necklaces or jewelry, be mindful of balance and color harmony! A common mistake is overcrowding the design with too many bead types or sizes, which can overwhelm the visual appeal. Instead, aim for a cohesive design, blending various shapes and colors to create a striking yet elegant piece that showcases your unique style!
