Answer :
Sure! Let's work through each of these decimal operations step-by-step:
a. Evaluate [tex]\(18.3 - 7.24 + 39.8\)[/tex]:
1. Subtract 7.24 from 18.3:
[tex]\[
18.3 - 7.24 = 11.06
\][/tex]
2. Add 39.8 to the result:
[tex]\[
11.06 + 39.8 = 50.86
\][/tex]
So, the result is 50.86.
b. Multiply [tex]\(15.6 \times 42.5\)[/tex]:
- When multiplying these two numbers, we get:
[tex]\[
15.6 \times 42.5 = 663.0
\][/tex]
The result is 663.0.
c. Divide [tex]\(38.4 \div 2.2\)[/tex]:
- To divide 38.4 by 2.2:
[tex]\[
38.4 \div 2.2 = 17.454545454545453
\][/tex]
The result is approximately 17.45 when rounded to two decimal places.
d. Add [tex]\(3 + 4.2 + 6.5 + 8.93\)[/tex]:
1. Start by adding 3 and 4.2:
[tex]\[
3 + 4.2 = 7.2
\][/tex]
2. Add 6.5 to the result:
[tex]\[
7.2 + 6.5 = 13.7
\][/tex]
3. Finally, add 8.93 to the result:
[tex]\[
13.7 + 8.93 = 22.63
\][/tex]
So, the result is 22.63.
These are the results for each of the operations!
