Question

which number do you think is a reasonable estimate for $48\div9$? lets play \make it reasonable!\ first, make an expression that is close to $48\div9$ and easier to solve. choose the number that is a multiple of 9. round 3: estimate $187\div6$. first, make an expression that is close to $187\div6$ and easier to solve. choose the number that is a multiple of 6. ? $\div6$

Explanation:

For the first question (estimating \(48 \div 9\)):

Step1: Find multiple of 9 near 48

Multiples of 9: \(9, 18, 27, 36, 45, 54, \dots\). 45 is closest to 48.

Step2: Calculate \(45 \div 9\)

\(45 \div 9 = 5\). So a reasonable estimate for \(48 \div 9\) is 5 (since \(48\) is close to \(45\), the quotient is close to 5).

For the "Round 3: Estimate \(187 \div 6\)" question:

Step1: Find multiple of 6 near 187

Multiples of 6: \(6, 12, \dots, 186, 192, \dots\). 186 is closest to 187.

Step2: Determine the expression

So the expression is \(186 \div 6\).

Answer:

s:

• Reasonable estimate for \(48 \div 9\): \(5\)
• Expression for estimating \(187 \div 6\): \(186 \div 6\)
