Answer 2

Question 1 -

$\tt\:56.8 \div 10 =~?$

‎

Solution -

$\tt\:56.8 \div 10$

Converting ÷ into ×

$\tt\implies\:56.8 \times \frac{1}{10}$

Converting decimal in fraction form

$\tt\implies\:\frac{568}{10} \times \frac{1}{10}$

Multiplying the terms

$\tt\implies\:\frac{568}{100}$

Converting fraction in decimal

$\large{\mathfrak\red{\implies\:5.68}}$

Points to remember :

• Whenever we divide fraction or divide the number with decimal point, the division sign is converted to multiplication and the other fraction is turned upside down.

• We must also know how to convert decimal in fraction form and vice versa.
