Step-by-Step Solution

Answer

The simplified form of $-38.9+24.2$ is $-14.7$.

Step 1.

The statement “$-38.9+24.2$.”

Step 2. Concept.

When one positive and one negative number are added than the absolute difference between the two is taken and the sign of the greater number is put in front of it.

Step 3. Calculation.

Consider the provided statement “$-38.9+24.2$.”

 

Recall that when one positive and one negative number are added then the absolute difference between the two is taken and the sign of the greater number is put in front of it.

 

So, the given expression can be simplified as,

$-38.9+24.2=-\left(38.9-24.2\right)$

$-38.9+24.2=-14.7$

Hence, the simplified form of $-38.9+24.2$ is $-14.7$.
