Question

Explain the process

3times of 25/81

Answer 1

three times of this means 25/81 x 3

=75/81

=25/27

Answer 2

The value of 3 times of $\dfrac{25}{81}$ is $\dfrac{25}{27}$.

Step-by-step explanation:

We have,

3 times of $\dfrac{25}{81}$

To find, the value of $\dfrac{25}{81}=?$

∴ $3 \times \dfrac{25}{81}$

$=3 \times \dfrac{5^{2} }{3^{4}}$

$=\dfrac{3}{3^{4}} \times {5^{2}$

$=3^{1-4} \times {5^{2}$

[ ∵ $\dfrac{a^{m}}{a^{n}} =a^{m-n}$]

$=3^{-3} \times {5^{2}$

$=\dfrac{25}{27}$

Hence, the value of 3 times of $\dfrac{25}{81}$ is $\dfrac{25}{27}$.
