Question

which expression can be represented by the model? 1.8÷4 1.8÷3 2÷5 2÷4

Explanation:

Step1: Analyze the model (assuming the model represents dividing a total of 1.8 into 3 parts)

Looking at the model, if we consider the total quantity related to 1.8 and dividing it into 3 equal parts, the expression would be \(1.8\div3\). Let's check other options: \(1.8\div4\) would be dividing 1.8 into 4 parts, \(2\div5\) and \(2\div4\) involve 2 as the dividend which doesn't match the model's context (assuming the model is about 1.8).

Step2: Confirm the correct expression

Among the given options, \(1.8\div3\) is the one that fits the model's representation of dividing 1.8 into 3 parts.

Answer:

\(1.8\div3\) (corresponding to the option: 1.8 ÷ 3)
