Oliver has 5 pieces of string that are each 4 2/12 feet long. Destiny has 4 pieces of string that are each 5 14/16 feet long. Use an estimation strategy to determine who has the most string.

_____ is estimated to have __ more feet of string.

Oliver has 5 strings that are approximately 4 feet each, so he has about 20 feet of string in total (5 strings x 4 feet = 20 feet).

Destiny has 4 strings that are approximately 6 feet each, so she has about 24 feet of string in total (4 strings x 6 feet = 24 feet).

So, Destiny is estimated to have 4 more feet of string than Oliver.
