Answer 1

Answer:

$\frac{57}{45} = \frac{57 \times 1}{45 \times 1} = \frac{57}{45}$

$\frac{25}{9} = \frac{25 \times 5}{9 \times 5} = \frac{125}{45}$

$\frac{57}{45} - \frac{125}{45} = \frac{57 - 125}{45} = - \frac{68}{45} = - 1 \frac{23}{45}$

Step-by-step explanation:

As 57 and 45 both are divisible by 3 we will first simplify it

So,

= 19/15-25/9

taking LCM

= 57-125

45

= -68
