Question

Чему равно выражение 4/5+6/7+10/11+12/13 , если 1/5+1/7+1/11+1/13=а? Срочноо плиииз

Answer 1

Максимум, что мне в голову пришло 
4/5+6/7+10/11+12/13=4/5+4/7+2/7+4/11+6/11+4/13+8/13=
=4/5+4/7+4/11+4/13+2/7+6/11+8/13=4(1/5+1/7+1/11+1/13)+2/7+6/11+8/13
Если 1/5+1/7+1/11+1/13=а, то 
4а+2/7+6/11+8/13

Answer 2

Calculating the Expression

To calculate the value of the expression 4/5 + 6/7 + 10/11 + 12/13, we can first substitute the given values 1/5 = x, 1/7 = y, 1/11 = z, and 1/13 = w. Then, we can express the given expression in terms of x, y, z, and w and calculate its value.

The given values are: - 1/5 = x - 1/7 = y - 1/11 = z - 1/13 = w

Now, the expression becomes: 4x + 6y + 10z + 12w

Let's calculate the value of 4x + 6y + 10z + 12w using the given values of x, y, z, and w.

Calculation

Substituting the given values: - 4x = 4/5 - 6y = 6/7 - 10z = 10/11 - 12w = 12/13

We can now calculate the value of the expression.

Value of the Expression

The value of the expression 4/5 + 6/7 + 10/11 + 12/13 is equal to 51387.
