Answer 2

Answer: $1\dfrac{1}{6}$

Step-by-step explanation:

• Dividing a fraction number by another fraction number is exactly same as to find the product of the first fraction and the reciprocal of the second fraction.

Therefore , if we divide $\dfrac{3}{18}$ by $\dfrac{7}{21}$, then it is actually equals to the product of  $\dfrac{3}{18}$  and reciprocal of $\dfrac{7}{21}$.

Reciprocal of $\dfrac{7}{21}=\dfrac{21}{7}=\dfrac{3}{1}=3$.

Now, $\dfrac{3}{18}\div\dfrac{7}{21}=\dfrac{3}{18}\times\dfrac{7}{21}$

$=\dfrac{1}{6}\times7=\dfrac{7}{6}=1\dfrac{1}{6}$

Hence, the answer is $1\dfrac{1}{6}$
