Answer :
Let's solve each part of the question step by step.
1. Calculate [tex]\(39.4 + (-7.2)\)[/tex]:
When you add a negative number, it's like subtracting the positive version of that number. So, this problem becomes:
[tex]\[
39.4 - 7.2
\][/tex]
Now, subtract 7.2 from 39.4:
[tex]\[
39.4 - 7.2 = 32.2
\][/tex]
So, [tex]\(39.4 + (-7.2)\)[/tex] equals 32.2.
2. Calculate [tex]\(6.7 - 39.31\)[/tex]:
This is a straightforward subtraction problem. You need to subtract 39.31 from 6.7. Since 39.31 is larger than 6.7, the result will be negative.
Let's perform the subtraction:
[tex]\[
6.7 - 39.31
\][/tex]
When you subtract, it’s like finding the difference between these two values:
[tex]\[
6.7 - 39.31 = -32.61
\][/tex]
Therefore, [tex]\(6.7 - 39.31\)[/tex] equals -32.61.
In summary, the answers are:
- [tex]\(39.4 + (-7.2) = 32.2\)[/tex]
- [tex]\(6.7 - 39.31 = -32.61\)[/tex]
