Step-by-step explanation:

• 1&6/7 × 3&1/3
• = (7×1)+6/7 × (3×3)+1/3
• = 13/7 × 10/3
• = 130/21
• = 6&10/21

Answer 2

Answer:

130/21

Step-by-step explanation:

$\boldsymbol{1\dfrac{6}{7} \times 3\dfrac{1}{3}}$

Convert the given mixed fraction into improper fraction.

$\dashrightarrow \: \: \sf{\dfrac{(7\times 1)+6}{7}\times \dfrac{(3 \times 3) + 1}{3}}$

$\implies \sf{\dfrac{13}{7}\times \dfrac{10}{3}}$

$\implies \sf{\dfrac{13 \times 10}{7 \times 3}}$

On multiplying,

$\implies \sf{\dfrac{130}{21}}$

$\therefore \: \: \boxed{\bf{1\dfrac{6}{7}\: \times \: 3\dfrac{1}{3}=\dfrac{130}{21}}}$

NOTE:

• For multiplying fractions, do not take LCM of denominators.
• But while adding or subtracting fractions, we need to take LCM of denominators.
