The third expression, −1.3−(4.9+2.6), is the expression that is equivalent to −1.3+(−4.9)+(−2.6)
From the question, the given expression is −1.3+(−4.9)+(−2.6). First, let us simplify this expression.
First, clear the brackets
−1.3+(−4.9)+(−2.6) = − 1.3 − 4.9 − 2.6
Then, − 1.3 − 4.9 − 2.6 = − 8.8
Now, we will check for the option that gives this answer (−8.8) when simplified.
Simplify by clearing the brackets, we get
−1.3 + 4.9 − 2.6 = 1
This does not corresponds to the given expression
Simplify by clearing the brackets, we get
−1.3 + 4.9 + 2.6 = 6.2
This does not corresponds to the given expression
Simplify by clearing the brackets, we get
−1.3 − 4.9 − 2.6 = − 8.8
This corresponds to the given expression, hence, it is equivalent to the given expression
Simplify by clearing the brackets, we get
1.3+4.9+2.6 = 8.8
This does not corresponds to the given expression
