Question

Kindly answer all three questions, thank you.

Answer 1

Concept :-

Here, we are given two fractions to divide. We know that how to divide the fractions. To divide two fractions, first we should take the reciprocal of the second fraction and then we should multiply both the fractions to obtain the answer. If the given number is a whole number, convert it to the fraction always.

➤ Formula required :-

${\large \tt \dashrightarrow \orange{\boxed{\tt \gray{\dfrac{a}{b} \div \dfrac{c}{d} = \dfrac{a}{b} \times \dfrac{d}{c}}}}}$

$\:$

➤ Solution (1) :-

${\tt \longrightarrow 3 \div 2 \dfrac{1}{3}}$

${\tt \longrightarrow \dfrac{3}{1} \div \dfrac{7}{3}}$

${\tt \longrightarrow \dfrac{3}{1} \times \dfrac{3}{7} = \dfrac{3 \times 3}{1 \times 7}}$

${\tt \longrightarrow \dfrac{9}{7} = 1 \dfrac{2}{7}}$

$\:$

➤ Solution (2) :-

${\tt \longrightarrow \dfrac{4}{9} \div 15}$$\:$

${\tt \longrightarrow \dfrac{4}{9} \div \dfrac{15}{1}}$

${\tt \longrightarrow \dfrac{4}{9} \times \dfrac{1}{15} = \dfrac{4 \times 1}{9 \times 15}}$

${\tt \longrightarrow \dfrac{4}{135}}$

$\:$

➤ Solution (3) :-

${\tt \longrightarrow 4 \dfrac{3}{7} \div 14}$

${\tt \longrightarrow \dfrac{31}{7} \div \dfrac{14}{1}}$

${\tt \longrightarrow \dfrac{31}{7} \times \dfrac{1}{14} = \dfrac{31 \times 1}{7 \times 14}}$

${\tt \longrightarrow \dfrac{31}{98}}$

$\:$

More to know :-

• While adding or subtracting the fractions, if they are unlike fractions we should convert them into like fractions by taking the LCM of the denominators and then add them.
• But while multiplying or dividing the fractions, it's not necessary to convert them into like fractions. But we should take the reciprocal of second fraction and multiply both (only for division), not necessary for multiplication.
