Question

21/19÷3/7= find the quotient​

Answer 1

Here's what you had asked for:

$\frac{21}{19}$ ÷ $\frac{3}{7}$

So as we can't divide this nos, we'll reciprocate (⇅) $\frac{3}{7}$ to $\frac{7}{3}$ for multiplication.

$\frac{21}{19}$ × $\frac{7}{3}$

Now, simplify them.

$\frac{7}{19}$ × $\frac{7}{1}$ = $\frac{49}{19}$
