Question

Question 1 : what means to make a fraction as simple as possible? we also call it reducing.

Answer 1

This means making the fraction reduced to its lowest term
example= 
make the fraction 18xz/4z simpler
the z cancels each other making it remaining 18x/4
2 can go in x as in 18
=9x/2
so the simpler form of the fraction 18xz/4z
=9x/2
