Question

evaluate 1+(-2/3)-(-m) where m=9/2

Answer 1

First substitute m with 9/2:

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

Next, calculate the subtraction within the parentheses:

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

To add the fractions, find a common denominator. The least common denominator in this case is 6:

1 * 6/6 + (-2 * 2/2) + (9 * 3/3)
= 6/6 - 4/6 + 27/6
= (6 - 4 + 27)/6
= 29/6

So, 1 + (-2/3) - (-m) where m=9/2 evaluates to 29/6.
