Answer:Kyle’s claim is not reasonable

Total length of the string of the necklace that Kyle covered with white beads is 1/4.

Total length of the string of the necklace that Kyle covered with black beads and white beads is would be

1/4 + 5/8 = 7/8 = 0.875

It means that he covered more than 6/12. Kyle's claim was wrong
