Question

1 + (-2/3) - (9/2) evaluate

Answer 1

Use the least common denominator(LCD) to solve this equation:

1 + (-2/3) - (9/2)

so, what is the LCM of 3 and 2 : 6

so, the LCD = 6

1 + (-2 x 2/6) - (9 x 3/6)

the 1 = 6/6

Put it back into the equation:

6/6 + (-4/6) - (27/6)

Then, take it out of the parenthesis:

6/6 - 4/6 - 27/6

Simplify:

= - 25/6

which is the answer.

Hope that helped !! Have a great day now

Answer 2

Evaluate 1 + (-2/3) - (-9/2):

It's safe to remove the parentheses, as follows:  1 - 2/3 + 9/2.  Recognizing that the LCD is 3(2) = 6, let's mult. this whole expression by 6 and then div. the result by 6:

6  -  4  + 27

------------------- =  29/6  (answer)

         6
