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

[tex]\[
\begin{array}{l}
1,400 \times 10 \\
140,000 \div 100 \\
1,400 \times 100
\end{array}
\][/tex]

A. 140,000
B. 1,400
C. 140
D. 14,000



Answer :

Let's evaluate each of the given mathematical expressions step-by-step and compare the results to the provided numbers: 140,000, 1,400, 140, and 14,000.

### Step 1: Evaluate the first expression
[tex]\[ 1,400 \times 10 \][/tex]

Multiplying [tex]\( 1,400 \)[/tex] by [tex]\( 10 \)[/tex]:
[tex]\[ 1,400 \times 10 = 14,000 \][/tex]

### Step 2: Evaluate the second expression
[tex]\[ 140,000 \div 100 \][/tex]

Dividing [tex]\( 140,000 \)[/tex] by [tex]\( 100 \)[/tex]:
[tex]\[ 140,000 \div 100 = 1,400 \][/tex]

### Step 3: Evaluate the third expression
[tex]\[ 1,400 \times 100 \][/tex]

Multiplying [tex]\( 1,400 \)[/tex] by [tex]\( 100 \)[/tex]:
[tex]\[ 1,400 \times 100 = 140,000 \][/tex]

Now, summarize the results of each expression:
1. [tex]\(1,400 \times 10 = 14,000\)[/tex]
2. [tex]\(140,000 \div 100 = 1,400\)[/tex]
3. [tex]\(1,400 \times 100 = 140,000\)[/tex]

### Step 4: Compare the given numbers

The results from our calculations are: 14,000, 1,400, and 140,000. Let's list the given numbers again:
- 140,000
- 1,400
- 140
- 14,000

We notice that:
- 140,000 matches [tex]\(1,400 \times 100\)[/tex]
- 1,400 matches [tex]\(140,000 \div 100\)[/tex]
- 14,000 matches [tex]\(1,400 \times 10\)[/tex]

However, the number 140 does not match any of the given expressions.

Thus, the number that is not equal to any of the expressions is:
[tex]\[ \boxed{140} \][/tex]
