Explanation:

$\frac{2}{5} \: of \: 0.6 + \frac{2.4}{8} - 0.2$

$= > \frac{2}{5} \times 0.6 + \frac{2.4}{8} - 0.2$

$= > \frac{12}{50} + \frac{24}{80} - 0.2$

$= > \frac{6}{25} + \frac{12}{40} - \frac{2}{10}$

$= > \frac{6}{25} + \frac{3}{10} - \frac{2}{10}$

L.C.M OF 25 AND 10 IS 50:-

$= > \frac{6 \times 2 + 3 \times 5 - 2 \times 5}{50}$

$= > \frac{12 + 15 - 10}{50}$

$= > \frac{27 - 10}{50} = \frac{17}{50} = 0.34$

Concept:

• We can remove decimal Point by 0.

if you have decimal on either numerator or denominator you ean remove by inserting 0.count the number of decimal point value and put number of zeroes to its opposite if decimal is in numerator then put the number of Zeroes in the denominator.
