<u>Answer-</u>

$-70\%$

<u>Solution-</u>

The given data as follows,

$-70\%,\ 0.34,\ -\dfrac{2}{5},\ 0.96\%$

After converting all the percentages and fractions to decimal, we can compare them all.

For converting percentages to decimal to divide the number by 100, so

$-70\%=\dfrac{-70}{100}=-0.70,\\\\0.96\%=\dfrac{0.96}{100} =0.0096$

Then converting the fraction into decimal,

$-\dfrac{2}{5}=-\dfrac{2\times 20}{5\times 20}=-\dfrac{40}{100}=-0.40$

As, all the numbers are converted into decimal, now comparing all the numbers,

$-0.70$

$-70\%$

Answer:

y = 1

Step-by-step explanation:

Recognize that 25 and 125 are powers of 5 and rewrite the equation in terms of powers of 5.

The applicable rules of exponents are ...

(a^b)^c = a^(bc)

(a^b)/(a^c) = a^(b-c)

(a^b)(a^c) = a^(b+c)

Your equation can be written as ...

$25^4\div5^{5y}=125^y\\\\(5^2)^4\div5^{5y}=(5^3)^y\\\\5^{8-5y}=5^{3y}\\\\8-5y=3y\qquad\text{equate exponents of the same base}$

Now this can be solved as an ordinary linear equation.

8 = 8y . . . . . . add 5y to both sides

1 = y . . . . . . . divide by 8

The solution is y = 1.
