Final answer:
The letter 'L' in the model for multiplying 26 by 54 represents the number 26, which consists of 2 tens and 6 ones, making Option A the correct choice.
Step-by-step explanation:
The student is asking about a model that can be used to multiply two numbers, specifically 26 and 54. In this context, the letter 'L' in the model likely stands for the place value representation of the number 26.
The number 26 consists of 2 tens (20) and 6 ones. Therefore, the correct representation for 'L' in this model is Option A: 2 tens and 6 ones. This is because when representing numbers in terms of tens and ones, we count the tens first, which in the case of 26 would be two, followed by the ones, which is six.
