Which expression has an estimated product of [tex]$45$[/tex]?

A. [tex]$44.7 \times 2.1$[/tex]

B. [tex]$75 \times 8.4$[/tex]

C. [tex]$87 \times 5.28$[/tex]

D. [tex]$38.1 \times 7.3$[/tex]

Answer :

To find which expression has an estimated product of 45, let's look at the options one by one:

1. Expression 1: 44.7 × 2.1
- The calculated product is 93.87.
- 93.87 is much higher than 45.

2. Expression 2: 75 × 8.4
- The calculated product is 630.0.
- This is also much higher than 45.

3. Expression 3: 87 × 5.28
- The calculated product is 459.36.
- This is again much higher than 45.

4. Expression 4: 38.1 × 7.3
- The calculated product is 278.13.
- This is significantly higher than 45.

Since none of these expressions result in a product close to 45 based on our calculated values, it seems like there might not be an expression among these that matches the estimated product of 45 accurately.
