Final answer:
Ryan is correct because he factored out the greatest common factor, while Jane's answer does not properly simplify the expression.
Step-by-step explanation:
Ryan is correct because he factored out the greatest common factor. By factoring out the greatest common factor, Ryan transformed the expression 32m - 24 into 4(8m - 6). This is valid because both 32 and 24 are divisible by 8.
Jane's answer, 8(4m - 3), is not a correct factorization. It does not properly simplify the expression and does not factor out the greatest common factor.
Therefore, option 1 is correct, and Ryan is the only one who correctly factored the expression.
