Question

Choose the equivalent expression.
23.4−41.2

23.4+41.2

−23.4+(−41.2)

23.4+(−41.2)

Answer 1

To choose the equivalent expression to \( 23.4 - 41.2 \), we can rewrite the subtraction as the addition of a negative number:

\[ 23.4 - 41.2 = 23.4 + (-41.2) \]

Now we can analyze the options given:

1. \( 23.4 - 41.2 \) (this is the original expression)
2. \( 23.4 + 41.2 \) (not equivalent)
3. \( -23.4 + (-41.2) \) (not equivalent)
4. \( 23.4 + (-41.2) \) (this is equivalent)

Therefore, the correct equivalent expression is:

**\( 23.4 + (-41.2) \)**
