Question

4целых 3/7+2 2целых 11/14

Answer 1

Превращаем в неправильную дробь
4 целых 3/7 = 31/7
2 целых 11/14 = 39/14
31/7 - 39/14 = (62 - 39)/14 = 23/14 = 1 целая 9/14

Answer 2

Равно неправильной дробью 381\14= 27 целых 3/14

Answer 3

To add the two mixed numbers, you need to convert them to improper fractions and then add them together. Here's the step-by-step calculation:

Step 1: Convert the mixed numbers to improper fractions.

• 4 целых 3/7 can be written as (4 * 7 + 3)/7 = 31/7
• 2 целых 11/14 can be written as (2 * 14 + 11)/14 = 39/14

Step 2: Add the improper fractions. 31/7 + 39/14

Step 3: Find a common denominator (the least common multiple of 7 and 14, which is 14). Now we need to rewrite both fractions with a common denominator:

31/7 = (31/7) * (2/2) = 62/14 39/14 (already in the right form)

Step 4: Add the fractions. 62/14 + 39/14 = (62 + 39)/14 = 101/14

Step 5: Convert the resulting improper fraction back to a mixed number. Divide 101 by 14: 101 ÷ 14 = 7 with a remainder of 3

The result is 7 целых 3/14.
