Final answer:
The student is asking to simplify an algebraic expression, but without further context, a precise solution cannot be provided. It involves combining like terms and simplifying fractions, assuming there are no typos in the original question.
Step-by-step explanation:
The student's question involves simplifying an algebraic expression which is a skill typically covered in high school mathematics. The expression provided is 9/8m + 9/10 - 2m - 3/5. The goal here is to combine like terms and simplify the expression as much as possible. Unfortunately, without further context or clarification, it is not possible to provide a fully accurate solution because it is unclear if the fractions are meant to be coefficients of variables or if they are standalone numerical terms. Additionally, it is unclear if there is a typo in the first term - whether it should be (9/8)*m or just 9 divided by 8m. If we assume the fractions are coefficients and there are no typos, the expression would simplify by combining the m terms and the numerical terms separately:
- Combine the m terms: (9/8)m - 2m
- Combine the numerical terms: 9/10 - 3/5
However, without clear terms, a precise answer cannot be given. In actual practice, one would clear the fractions or convert all terms to have a common denominator and then simplify accordingly.
