Answer 1

1. 1 / 16/9 = 1 / 1целая7/9

2. 1 / 25/4 = 1/ 6целых1/4

3. 1 / 64/49 = 1 / 1целая15/49

Answer 2

To simplify the expressions, let's first recall the rule that when you raise a fraction to a negative exponent, you can flip the fraction and change the sign of the exponent. So, for any fraction $a/b$, $(a/b)^{-n} = (b/a)^n$.

Now, let's simplify each expression:

1. $(4/3)^{-2} = (3/4)^2 = 9/16$

2. $(5/2)^{-2} = (2/5)^2 = 4/25$

3. $(8/7)^{-2} = (7/8)^2 = 49/64$

So, the simplified values are:

1. $(4/3)^{-2} = 9/16$

2. $(5/2)^{-2} = 4/25$

3. $(8/7)^{-2} = 49/64$
