4целых 4/12+ 13целых 4/5-5целых5/6+7целых9/11​

Answer 1

Ответ:

20 13/110

Пошаговое объяснение:

4 4/12 + 13 4/5 - 5 5/6 + 7 9/11 =

1) 4 4/12 + 13 4/5 = 4 20/60 + 13 48/60 = 17 68/60

2) 17 68/60 - 5 5/6 = 17 68/60 - 5 50/60 = 12 18/60

3) 12 18/60 + 7 9/11 = 12 198/660 + 7 540/660 = 20 13/110

Answer 2

1) 17 целых 4/13
2) 2 целых 259/230

Answer 3

To solve the given expression, let's break it down step by step:

1. Simplify the fractions:

   • 4/12 can be reduced to 1/3 because both the numerator and denominator are divisible by 4.
   • 4/5 cannot be simplified further.

2. Convert the mixed numbers to improper fractions:

   • 13 4/5 = (13 * 5 + 4) / 5 = 69/5
   • 5 5/6 = (5 * 6 + 5) / 6 = 35/6
   • 7 9/11 = (7 * 11 + 9) / 11 = 86/11

Now let's substitute the simplified fractions and improper fractions back into the expression:

1/3 + 69/5 - 35/6 + 86/11

To add or subtract fractions, we need a common denominator. In this case, the least common denominator (LCD) is 3 * 5 * 6 * 11 = 990.

Now we can rewrite each fraction with the common denominator:

(1/3) * (330/330) + (69/5) * (198/198) - (35/6) * (165/165) + (86/11) * (90/90)

This gives us:

330/990 + 13842/990 - 5775/990 + 7740/990

Now we can add or subtract the fractions:

(330 + 13842 - 5775 + 7740) / 990

Simplifying the numerator:

(19937) / 990

The fraction cannot be simplified any further, so the final answer is:

19937/990
