Two students were asked to graph the rational number -7.1. amy states that the number is between -8 and -7, but laura states that the point is between -7 and -6. how can you determine which student is correct?

Amy is correct, -7.1 is between -7 and -8.  We know this because in order for it to be in between -6 and -7, the number would have to be a decimal with a whole number of 6 (for example, 6.3 or 6.7).  But -7.1 has a whole number of 7 so it is in between -7 and -8

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
