Answer 2

can you work it out for me please because i have to show my work and i really dont get it, thankyou

Answer 3

\[\frac{2}{9}-\frac{2}{15}=N\]

now lets just start clearing the fractions from low to high; multiply thru by 9

\[\frac{2(9)}{9}-\frac{2(9)}{15}=(9)N\]
\[2-\frac{2(3)}{5}=9N\]

now multiply thru by 5

\[2(5)-\frac{2(3)(5)}{5}=9(5)N\]
\[2(5)-2(3)=9(5)N\]

then solve for N
