Question

1)3 3/10-1 7/15 2)8 7/8-4 5/6​

Answer 1

Ответ:  3 3\10 -1 7-5 = 3   9\30  - 1  14\30 = 2   29\30 -  1  14 \ 30 = 1   25  \ 30 .

Answer 2

To subtract mixed numbers like the ones you provided, follow these steps:

1. 3 3/10 - 1 7/15:

First, find a common denominator for 10 and 15, which is 30. Then, convert both fractions to have a denominator of 30:

3 9/30 - 1 14/30

Now, subtract the whole numbers and fractions separately:

3 - 1 = 2 9/30 - 14/30 = -5/30

Combine the whole number and fraction:

2 - 5/30

Now, simplify the fraction by dividing both the numerator and denominator by their greatest common factor, which is 5:

2 - (5/5) * (1/30)

2 - 1/6

So, 3 3/10 - 1 7/15 = 1 5/6.

2. 8 7/8 - 4 5/6:

First, find a common denominator for 8 and 6, which is 24. Then, convert both fractions to have a denominator of 24:

8 21/24 - 4 20/24

Now, subtract the whole numbers and fractions separately:

8 - 4 = 4 21/24 - 20/24 = 1/24

Combine the whole number and fraction:

4 1/24

So, 8 7/8 - 4 5/6 = 4 1/24.
