When you simplifying complex fractions, factor the numerator and denominator into terms multiplying each other and look for equivalents of one (something divided by itself). Include parenthesis around any expression with a “+” or “-” and if all terms cancel in the numerator, there is still a one (1) there.

Hey I was just wondering how does the 9 turn into 3 and the 3 turns into 1 do you divide both by the numerator of the first fraction (3) ?

He is reducing the fraction at that point.

Since you have 3/5 x 7/9 , it is the same as 3/9 x 7/5.

Reduce the 3/9. It becomes 1/3.

Then you have 1/3 x 7/5. Multiply across and you get 7/15.
