Answer: Tina has 3/4 more coconut than Betty.
Step-by-step explanation:
The total number of coconuts that they picked is 9.
If Betty takes the 5 lightest coconuts, then the weights of each coconut that she took would be
1 lb × 2 = 2 lbs
1 1/4lb × 1 = 5/4 lbs
1 1/2lb × 2 = 3/2 × 2 = 3 lbs
The total number of pounds of coconut that Betty took is
2 + 5/4 + 3 = 25/4 lbs
If Tina would have the rest, then the weights of each coconut that she took would be
1 1/2 lb × 1 = 3/2 × 1 = 3/2 lb
1 3/4 lbs × 2 = 7/4 × 2 = 7/2 lbs
2 lbs × 1 = 2lbs
The total number of pounds of coconut that Tina took is
3/2 + 7/2 + 2 = 14/2 = 7 lbs
Therefore, Tina has more coconut by weight. The difference in the weights is
7 - 25/4 = 3/4 lb
