There's no cross multiplying involved in calculating (2/3)*9 ,

Answer 10

Answer 11

You only cross multiply if you have a proportion:

\[\dfrac{a}{b} = \dfrac{c}{d}\]
\[ad = bc\]

Answer 12

This is what you're multiplying:

\[\dfrac{2}{3} \times \dfrac{9}{1}\]

You multiply the numerators first. Then the denominators
