Answer 1

1)(7/11+4/11)х425=425

2)(1 2/3+8 1/3)х548=10х548=5480

3)658:(1 2/9+7/9)=658:2=329

4)360:(2 4/9+7 5/9)=360:10=36

Answer 2

1)   (7/11+4/11)*425=1*425=425

2)   (1 целая 2\3+8 цел 1/3)*548=10*548=5480

3)   658:(1цел2/9+7/9)=658/2=329

4)   360:(2цел4/9+7цел5/9)=360/10=36

Answer 3

1) To solve the equation (1 + (7/11 + 4/11)) * 425, we can simplify the expression inside the parentheses first.

The sum of 7/11 and 4/11 is 11/11, which simplifies to 1.

So, the equation becomes (1 + 1) * 425.

Adding 1 and 1 gives us 2, and multiplying 2 by 425 gives us the final answer of 850.

2) Let's solve the equation (1 + целая 2/3 + 8 + цел 1/3) * 548.

First, we need to convert the mixed fractions into improper fractions.

The mixed fraction целая 2/3 can be written as 3/3 + 2/3, which simplifies to 5/3.

Similarly, цел 1/3 can be written as 3/3 + 1/3, which simplifies to 4/3.

Now, the equation becomes (1 + 5/3 + 8 + 4/3) * 548.

Adding the fractions inside the parentheses, we get (1 + 5/3 + 8 + 4/3) = 18/3 + 5/3 + 8 = 23/3 + 8.

To add these fractions, we need to find a common denominator, which is 3.

So, 23/3 + 8 can be written as (23 + 8 * 3)/3 = (23 + 24)/3 = 47/3.

Finally, multiplying 47/3 by 548 gives us the final answer of 8,036.

3) Let's solve the equation 658 / (1 целая 2/9 + 7/9).

First, we need to convert the mixed fraction into an improper fraction.

The mixed fraction 1 целая 2/9 can be written as 9/9 + 2/9, which simplifies to 11/9.

Now, the equation becomes 658 / (11/9 + 7/9).

Adding the fractions inside the parentheses, we get (11/9 + 7/9) = 18/9.

Dividing 658 by 18/9 is the same as multiplying 658 by the reciprocal of 18/9, which is 9/18.

So, 658 / (11/9 + 7/9) = 658 * (9/18) = 329 * 1/2 = 164.5.

4) Let's solve the equation 360 / (2 целая 4/9 + 7 целая 5/9).

First, we need to convert the mixed fractions into improper fractions.

The mixed fraction 2 целая 4/9 can be written as 9/9 + 4/9, which simplifies to 13/9.

Similarly, 7 целая 5/9 can be written as 9/9 + 5/9, which simplifies to 14/9.

Now, the equation becomes 360 / (13/9 + 14/9).

Adding the fractions inside the parentheses, we get (13/9 + 14/9) = 27/9.

Dividing 360 by 27/9 is the same as multiplying 360 by the reciprocal of 27/9, which is 9/27.

So, 360 / (13/9 + 14/9) = 360 * (9/27) = 360 * 1/3 = 120.

I hope this helps! Let me know if you have any further questions.
