During Monday, Tuesday and Wednesday, an organization donated several kilograms of rice to some families. On Monday, they delivered 29kg and on Tuesday, 38 1/4 kg. Between the 3 days, they distributed 115.75 kg. How many did they distribute on Wednesday?

To find out how many kilograms of rice the organization distributed on Wednesday, you can subtract the amounts distributed on Monday and Tuesday from the total amount distributed over the three days. Total distributed over three days = 115.75 kg Amount distributed on Monday = 29 kg Amount distributed on Tuesday = 38 1/4 kg To subtract the fractions, convert 38 1/4 to an improper fraction: 38 1/4 = (4 * 38 + 1) / 4 = 153/4 kg Now, subtract the amounts distributed on Monday and Tuesday from the total: Total distributed on Wednesday = Total distributed over three days - Amount distributed on Monday - Amount distributed on Tuesday Total distributed on Wednesday = 115.75 kg - 29 kg - 153/4 kg To subtract 29 kg and 153/4 kg, you'll need to have a common denominator, which is 4: Total distributed on Wednesday = (115.75 kg * 4/4) - (29 kg * 4/4) - (153/4 kg) Total distributed on Wednesday = (463/4 kg) - (116/4 kg) - (153/4 kg) Now, subtract the fractions: Total distributed on Wednesday = (463/4 - 116/4 - 153/4) kg Total distributed on Wednesday = (463 - 116 - 153) / 4 kg Total distributed on Wednesday = (194) / 4 kg Total distributed on Wednesday = 48.5 kg So, the organization distributed 48.5 kilograms of rice on Wednesday.
