Answer 1

Ответ:

Пошаговое объяснение:

1) 4/7 * (-35/6) =

2/1 * (-5/3) = -10/3 =

-3. 1/3

2) 5/62 * (-31/7) =

5/2 * (-1/7) = -5/14

3) -3. 1/3 - (-5/14) =

-3. 1/3 + 5/14 =

-3. 14/42 + 15/42 =

-2. 56/42 + 15/42 =

-2. 41/42

Answer 2

Ответ:

4/7 × (-35/6) - 5/62 × (-31/7)=​635/42

4/7*(-35/6)=-(4/7*35/6)=-(4/1*5/6)=-20/6

+(5/62*31/7)=5/2*1/7=5/14

-20/6+5/14=2 41/42

- -=+

Answer 3

To solve the expression, you can follow these steps:

1. Calculate the first part of the expression: (4/7) × (-35/6)
2. Calculate the second part of the expression: (5/62) × (-31/7)
3. Subtract the result from step 2 from the result in step 1.

Let's calculate it step by step:

1. (4/7) × (-35/6) = (4 * -35) / (7 * 6) = -140 / 42 = -70 / 21

2. (5/62) × (-31/7) = (5 * -31) / (62 * 7) = -155 / 434

3. Now, subtract the result from step 2 from the result in step 1:

(-70/21) - (-155/434)

To subtract these fractions, you need to find a common denominator, which is the least common multiple of 21 and 434, which is 434.

Now, convert both fractions to have a denominator of 434:

-70/21 = (-70 * 20) / (21 * 20) = -1400/434 -155/434

Now, subtract:

(-1400/434) - (-155/434) = (-1400 + 155) / 434 = -1245/434

So, the simplified result of the expression is -1245/434.
