<h3>What is division?</h3>

The division means the separation of something into different parts, sharing of something among different people, places, etc.

The expressions are (3.683 × 10⁴) and (7.51 × 10¹²).

We have to divide (3.683 × 10⁴) from (7.51 × 10¹²).

$\dfrac{3.683 * 10^4}{7.51*10^{12}}\\\\0.4904*10^{-8}\\\\4.9041*10^{-9}$

Solution:

0.3 × 2.7

Using Distributive property of multiplication with respect to subtraction the value of multiplication of two rationals or two decimals

⇒0.3 × (3-0.3)

⇒ 0.3 × 3 - 0.3 × 0.3

⇒ 0.9 - 0.09

= 0.81

H C F of 0.3 and 2.7 is 0.3.

The Equivalent of product of 0.3 × 2.7 are

1.→0.9 × 0.9

2.→→ 3 × 0.27
