Question

8 2/3+1 1/94 1/4+3 2/155 6/13-3 1/217 1/16-2 5/24​

Answer 1

Ответ:

8 2/3+1 1/9=9 7/9(приводи целое в дроби и потом находи общий знаменатель)

4 1/4+3 2/15=7 23/60

5 6/13-3 1/2=1 25/26

17 1/16-2 5/24=14 41/48.

везде применяй правило с выше

ВОТ ПРИМЕР ПОНЕМУ И РЕШАЙ.:8 2/3+1 1/9=26/3+10/9=(общий знаменатель 9.)3*26+10/9итого =88/9(неправильная дробь)значит 88:9=9 7/9 вот ответ.

Answer 2

To perform the addition and subtraction of these mixed numbers and fractions, you can follow these steps:

1. Find a common denominator for each set of fractions.
2. Perform the addition or subtraction of the fractions.
3. Combine the whole numbers with the results from step 2.

Let's go through the calculations:

1. Common denominator for 2/3 and 1/9 is 9.
2. (2/3 + 1/9) = (6/9 + 1/9) = 7/9

Now, combine with the whole numbers:

8 + 1 = 9

So, 8 2/3 + 1 1/9 = 9 7/9

Now, let's move on to the next set:

1. Common denominator for 1/4 and 2/155 is 620 (4 * 155).
2. (1/4 + 2/155) = (155/620 + 8/620) = 163/620

Now, combine with the whole numbers:

3 + 0 = 3

So, 3 1/4 + 3 2/155 = 3 163/620

Finally, let's deal with the last set:

1. Common denominator for 6/13 and 1/217 is 2809 (13 * 217).
2. (6/13 - 1/217) = (1638/2809 - 13/2809) = 1625/2809

Now, combine with the whole numbers:

0 - 3 = -3

So, 0 6/13 - 3 1/217 = -3 1625/2809

These are the results of the calculations.
