Answer 1

Complete question:

Multiple choice question (MCQ):

$0.2\times 0.2=$

• (a) $\dfrac{2}{10}$

• (b) $\dfrac{4}{10}$

• (c) $\dfrac{2\times 2}{100}$

• (d) $\dfrac{2\times 2}{10}$

Before we solve the problem, we must understand some algebra.

• $0.1=\dfrac{1}{10}$
• So, we can conclude that if there is a number in the tenths place, we have to divide the digit by $10$
• For example, $0.2=\dfrac{2}{10}$

Step-by-step explanation:

Now, $0.2\times 0.2$

$=\dfrac{2}{10}\times \dfrac{2}{10}$

$=\dfrac{2\times 2}{10\times 10}$

$=\bold{\dfrac{2\times 2}{100}}$

Answer: Option (c) $\boxed{\dfrac{2\times 2}{100}}$
