4 : 5
(three empty boxes)
(buttons: two colons, 8, 2, 6, 4, 10)

Explanation:

Step1: Understand ratio equivalence

A ratio \(a:b\) can be equivalent to \(ka:kb\) where \(k\) is a positive number. For \(4:5\), we can find equivalent ratios by multiplying both terms by the same factor.

Step2: Find equivalent ratio

Let's multiply both 4 and 5 by 2. So \(4\times2 = 8\) and \(5\times2 = 10\). So the equivalent ratio is \(8:10\).

Answer:

\(8:10\)
