Which of the following expressions represents a positive number? Choose all that apply. -2.25-(-3) or 2.3+(-2.4) or 4-(-2) or -1/2+(-3/4) or -7/8-(-6/7)

Respuesta :

Answer: 1 and 3

Step-by-step explanation:

-2.25 - (-3) = -2.25 + 3. Since 3 > 2.25, the expression is positive.

2.3 + (-2.4) = 2.3 - 2.4. Since 2.4 > 2.3, this expression is negative.

4 - (-2) = 4 + 2. This is positive as it adds two positives together.

-1/2 + (-3/4) = -1/2 - 3/4. Since this is a negative - negative, the expression is negative.

-7/8 - (-6/7) = -7/8 + 6/7. Since 7/8 > 6/7, the expression is negative.
-2.25-(-3) = 0.75
4-(-2) = 6
- these 3 only.
