Question

which number is a reasonable estimate for $87\div4$? 10 20 50 200

Explanation:

Step1: Simplify the division

First, we can approximate \(87\div4\). We know that \(80\div4 = 20\), and \(87\) is close to \(80\) but a bit larger. However, let's check the actual value: \(87\div4 = 21.75\). Now let's compare with the options. \(10\) is too small, \(50\) and \(200\) are way too large. \(20\) is the closest reasonable estimate since \(80\div4 = 20\) and \(87\) is near \(80\).

Answer:

20
