Question

Which two terms can be combined in this expression 6 + 3.2m + 2/5n - m/5

Answer 1

All the whole numbers can be combined, and also the like variables can be combined as well. (3.2m and -m)

Answer 2

3.2m and m/5

Explanation:

The terms that can be added are those that are like terms, that is, they have the same variable and with the same exponent.

In this case the only two terms that have the same variable in common are:

3.2m and m/5,

since to combine them we do not care about the coefficient they have, either decimal or fraction, the fact that they have the same variable (in this case the m) is enough to combine them.
