What is the missing value in the given mathematical statement?
$0.25\times 12 = 0.25 \times 3 + 0.25 \times 3 + 0.25\times$ ________.

maths decimal fraction multiplying decimals multiplication of decimals multiplication of division of decimal fraction by whole number and decimal fraction

  1. $2$

  2. $3$

  3. $6$

  4. $8$

Show answer
Correct Option: C
Explanation:

Using distributive property, we have
$0.25\times 12 = 0.25 \times (3 + 3 + 6)$
$\Rightarrow 0.25\times 12 = 0.25 \times 3 + 0.25\times 3 + 0.25 \times 6$.
