(-3 3/7+(-2 1/14))+(-3 1/2)

(-3 3/7+(-2 1/14))+(-3 1/2) = (-24/7 + (-29/14)) + (-7/2)

To simplify the expression, we first need to find a common denominator:

Denominator for 7 and 14 is 14, and for 7 and 2 is 14 as well.

Next, we convert the fractions to have a common denominator of 14:

(-24/7 + (-29/14)) + (-7/2) = (-48/14 + (-29/14)) + (-49/14)

Adding the numerators and using the common denominator, we get:

= (-48 - 29) / 14 + (-49/14) = -77/14 + (-49/14)

Finally, adding the numerators:

= (-77 - 49) / 14 = -126/14 = -9

The answer is -9.

Ответ: -9.
