Question 46

Solve $$\frac{12}{13}\times \frac{285}{96} \div \frac{171}{169}$$ = ?

Solution

$$\frac{12\ }{13}\times\frac{285\ }{96}\div\frac{171\ }{169}$$

$$=\frac{12\ }{13}\times\frac{285\ }{96}\times\frac{169\ }{171}$$

$$=\frac{1\ }{1}\times\frac{285\ }{8}\times\frac{13\ }{171}$$

$$=\frac{1\ }{1}\times\frac{15\ }{8}\times\frac{13\ }{9}$$

$$=\frac{1\ }{1}\times\frac{5\ }{8}\times\frac{13\ }{3}$$

$$=\frac{65\ }{24}$$

$$=2\frac{17\ }{24}.$$

B is correct choice.
