Answer:If the ratio of red, blue, and white beads in the necklace is 4:7:10, we can find the number of beads of each color by dividing the total number of beads (1050) into parts based on the ratio.
To do this, we add up the parts of the ratio (4 + 7 + 10 = 21) and divide the total number of beads by this sum.
Then, we multiply this quotient by each part of the ratio to find the number of beads for each color.
Step-by-step explanation:We can find the number of beads for each color by dividing the total number of beads (1050) into parts based on the ratio of 4:7:10. By doing this, we can determine how many beads of each color there are in the necklace.
