Answer 2

Answer:

2$\frac{7}{12}$ hours

Step-by-step explanation:

3$\frac{1}{3}$ = $\frac{10}{3}$

∴ total duration - advertisement time = duration of the film

= $\frac{10}{3}$ - $\frac{3}{4}$

LCM of 3 and 4 = 12

∴ $\frac{10}{3}$ x $\frac{4}{4}$ = $\frac{40}{12}$

∴ $\frac{3}{4}$  x $\frac{3}{3}$ = $\frac{9}{12}$

$\frac{40}{12}$ - $\frac{9}{12}$ = $\frac{31}{12}$

$\frac{31}{12}$ = 2$\frac{7}{12}$

∴ The film lasted 2$\frac{7}{12}$ hours
