The value of 12pi over 10pi times 5pi Over 6pi is closest to the whole number (blank). Find the blank

lisov135 [29]

Given:

The expression is

$\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}$

To find:

The value of the given expression closest to the whole number.

Solution:

We have,

$\dfrac{12\pi}{10\pi}\times \dfrac{5\pi}{6\pi}$

Cancel out the common factors from each fraction.

$=\dfrac{6}{5}\times \dfrac{5}{6}$

$=\dfrac{6\times 5}{5\times 6}$

$=\dfrac{30}{30}$

$=1$

Therefore, the value of the given expression is 1.
