Which expression will give a better estimate of [tex]$37.6 \div 11$[/tex]?

A. [tex]$30 \div 10$[/tex]
B. [tex]$40 \div 10$[/tex]

Use the expression you picked to estimate the quotient.

[tex]$37.6 \div 11$[/tex] is about [tex]\square[/tex].

Answer :

To find out which expression provides a better estimate for [tex]\(37.6 \div 11\)[/tex], we will evaluate the expressions [tex]\(30 \div 10\)[/tex] and [tex]\(40 \div 10\)[/tex] to see which is closer to the actual quotient.

1. First Expression: Evaluate [tex]\(30 \div 10\)[/tex].
- [tex]\(30 \div 10 = 3\)[/tex]

2. Second Expression: Evaluate [tex]\(40 \div 10\)[/tex].
- [tex]\(40 \div 10 = 4\)[/tex]

Now, we compare these estimates to the actual result of [tex]\(37.6 \div 11\)[/tex]:

3. Actual Division: Calculate [tex]\(37.6 \div 11\)[/tex].
- The actual result is approximately [tex]\(3.42\)[/tex].

4. Determine Which Estimate is Closer:
- Compare the distance between each estimate and the actual result.
- For [tex]\(30 \div 10 = 3\)[/tex], the difference is approximately [tex]\(0.42\)[/tex].
- For [tex]\(40 \div 10 = 4\)[/tex], the difference is approximately [tex]\(0.58\)[/tex].

Since the difference is smaller for [tex]\(30 \div 10 = 3\)[/tex], this estimate is closer to the actual quotient.

Therefore, the expression [tex]\(30 \div 10\)[/tex] gives a better estimate, so:
[tex]\[ 37.6 \div 11 \text{ is about } 3 \][/tex]
