Which number is not equal to one of the following expressions?

[tex]\[
\begin{array}{l}
0.5017 \times 1000 \\
501.7 \div 10 \\
501.7 \div 1000
\end{array}
\][/tex]

A. 50.17
B. 5.017
C. 0.5017
D. 501.7



Answer :

Let's evaluate each of the given expressions step-by-step:

1. Evaluate [tex]\(0.5017 \times 1000\)[/tex]:
[tex]\[ 0.5017 \times 1000 = 501.7 \][/tex]

2. Evaluate [tex]\(501.7 \div 10\)[/tex]:
[tex]\[ 501.7 \div 10 = 50.17 \][/tex]

3. Evaluate [tex]\(501.7 \div 1000\)[/tex]:
[tex]\[ 501.7 \div 1000 = 0.5017 \][/tex]

Now, we have calculated the values of the three expressions:
1. [tex]\(0.5017 \times 1000 = 501.7\)[/tex]
2. [tex]\(501.7 \div 10 = 50.17\)[/tex]
3. [tex]\(501.7 \div 1000 = 0.5017\)[/tex]

Next, let's compare these results to the options given:
- 50.17
- 5.017
- 0.5017
- 501.7

We observe that:
- 50.17 is equal to [tex]\(501.7 \div 10\)[/tex]
- 0.5017 is equal to [tex]\(501.7 \div 1000\)[/tex]
- 501.7 is equal to [tex]\(0.5017 \times 1000\)[/tex]

Clearly, 5.017 is the only number that does not match any of the evaluated expressions.

Therefore, the number that is not equal to one of the expressions is:
[tex]\[ \boxed{5.017} \][/tex]
