Question

Смешанные дроби сложение = 1 3/4 + 2 2/3 = 3 + 9/12 + 8/12 = 3 + 17/12 = 1 5/12 ИЛИ 3 + 1 + 5/12 = 4 5/12

Answer 1

$= 1 \frac{3}{4} + 2 \frac{2}{3} =1 \frac{9}{12} + 2 \frac{8}{12} = 3 \frac{17}{12} = 4 \frac{5}{12}$

Answer 2

Let's solve the expression step by step to find the correct result for the addition of mixed fractions.

1. First, we need to convert the mixed fractions into improper fractions: 1 3/4 = (4 * 1 + 3)/4 = 7/4 2 2/3 = (3 * 2 + 2)/3 = 8/3

2. Next, we find a common denominator, which in this case is 12 (the least common multiple of 4 and 3).

3. Now, we convert both fractions to have a denominator of 12: 7/4 = (7/4) * (3/3) = 21/12 8/3 = (8/3) * (4/4) = 32/12

4. Finally, we can add the two fractions: 21/12 + 32/12 = 53/12

Now, we have an improper fraction, 53/12. To convert it back to a mixed fraction:

5. Divide the numerator (53) by the denominator (12): 53 ÷ 12 = 4 with a remainder of 5.

So, the mixed fraction form of 53/12 is 4 5/12.

Therefore, the correct result of the addition of the mixed fractions 1 3/4 and 2 2/3 is 4 5/12, not 1 5/12 or 4 1/12.
