Answer 1

answer is

=(973/4)

Step-by-step explanation:

We have,

={−3

3

/4

3

)−(5

/2

)}×16

={(−27/64)−(−125/8)}×16

First we find the difference of {(−27/64)−(125/8)}

LCM of 64 and 8 is 64

⇒(−27×1)/(64×1)=(−27/64)

and ⇒(125×8)/(8×8)=(1000/64)

Now,

=(1000−(−27))/64

=(1000+27)/64

=(973/64)

So,

=(973/64)×16

=(973/4)
