2,3/8 + 5,5/6 =
8,5/24 is the sum of 2,3/8 and 5,5/6.
To add fractions, it is necessary to have a common denominator. In this case, the denominators 8 and 6 can both be converted to 24, facilitating the addition of the fractional parts. The whole numbers can be added separately.
This answer is incorrect as it considerably underestimates the sum of the whole numbers 2 and 5, which is 7. The sum of the fractions 3/8 and 5/6, when converted to 24 as a common denominator, results in 9/24 + 20/24 = 29/24 = 1,5/24. Therefore, the sum of the whole numbers and the fractions is 7 + 1,5/24 = 8,5/24.
This option is also incorrect. First, the sum of the whole numbers 2 and 5 is 7, but the sum of the fractions 3/8 and 5/6 is greater than 1 when converted to a common denominator. Moreover, 4/7 is not the correct sum of the fractions even if you use 7 as the common denominator.
This is the correct answer. The sum of the whole numbers 2 and 5 is 7. The fractions 3/8 and 5/6 convert to 9/24 and 20/24 respectively when using 24 as the common denominator. The sum of these fractions is 29/24, which simplifies to 1,5/24. Adding this to the sum of the whole numbers gives 8,5/24.
This answer is incorrect because 4/7 does not represent the correct sum of the fractions 3/8 and 5/6, even when using 7 as the common denominator. The correct sum is 1,5/24 when using 24 as the common denominator.
Adding fractions involves finding a common denominator and then adding the numerators to obtain the fractional part of the sum. The whole numbers are added separately. In this case, the sum of the whole numbers 2 and 5 is 7 and the sum of the fractions 3/8 and 5/6 is 1,5/24 when converted to a common denominator of 24. The correct sum is therefore 8,5/24.
