Question

(5 1/14-1 9/14)-(2 11/14+5/14)

Answer 1

Ответ:

1)5 1/14-1 9/14=4 1/14-9/14=3 15/14-9/14=3 6/14

2) 2 11/14+5/14=2 16/14=3 2/14

3)3 6/14-3 2/14=4/14=2/7

Answer 2

To subtract the given mixed numbers, follow these steps:

1. Subtract the whole numbers separately.
2. Subtract the fractions separately.
3. Combine the results from steps 1 and 2.

Let's break it down:

1. Subtract the whole numbers: 5 - 2 = 3.

2. Subtract the fractions:

   • For the first fraction, 1/14 - 9/14 = (-8/14).
   • For the second fraction, 11/14 + 5/14 = (16/14).

3. Now, subtract the fractions: (-8/14) - (16/14) = (-24/14).

So, the final result is:

3 - (24/14)

Now, let's simplify the fraction:

3 - (24/14) = 3 - (12/7)

To combine the whole number and the fraction, find a common denominator:

3 = 21/7

Now, subtract the fractions:

21/7 - 12/7 = 9/7

So, the result is:

9/7

You can also express this as a mixed number:

9/7 = 1 2/7

So, (5 1/14 - 1 9/14) - (2 11/14 + 5/14) = 1 2/7 or 9/7.
