$1. \text{ "(3a^2)/b" and " 2." } \frac{{b}^{3} {c}^{2}}{2}$

#### Explanation:

I will assume that the question is to simplify these two?

In Algebra, once you have identified what operation to do, use the approach of rarr "signs"?
color(white)(xxxxxxxx)rarr "numbers"?
color(white)(xxxxxxxx)rarr "variables and indices"?#

1) $\frac{21 {a}^{2}}{7 b} = \frac{3 {a}^{2}}{b} \text{ } \leftarrow$ only the numbers can be divided

2) $\frac{{b}^{3} {c}^{2}}{2} = \frac{{b}^{3} {c}^{2}}{2} \text{ } \leftarrow$ nothing simplifies - in simplest form
