Answer 2

Answer:   $\frac{12ch}{a}$

This is the same as writing (12ch)/a

===================================================

Explanation:

When multiplying fractions, we multiply the numerators together separately from the denominators.

$\frac{21c^2}{a}\times \frac{4h}{7c} = \frac{21c^2*4h}{a* 7c}$

Then notice the 21 over 7 reduces to 3.

Also, simplifying the c^2 over c part leads to c

Nothing else cancels.

We're left with this: $\frac{3c*4h}{a} = \frac{12ch}{a}$
