Models can be used to represent quotient of numbers by grouping the numbers.
The correct result of Rohan's model is 0.46
Rohan's model is represented as:
[tex]\mathbf{1.38 \div 3 = 0.43}[/tex]
The model is incorrect, and the correction is as follows:
Express 1.38 as 1.20 + 0.18
[tex]\mathbf{1.38 \div 3 = (1.20 + 0.18) \div 3}[/tex]
Split
[tex]\mathbf{1.38 \div 3 = 1.20 \div 3+ 0.18 \div 3}[/tex]
Divide
[tex]\mathbf{1.38 \div 3 = 0.40+ 0.06}[/tex]
[tex]\mathbf{1.38 \div 3 = 0.46}[/tex]
Hence, the correct result of the model is 0.46
