Question

ok look at the blue circle and tell me how did the 30 denominator went up in next step?​

Answer 1

it's a rule I explain you :-

if :-

$= > \frac{ \frac{5}{2} }{ \frac{4}{3} }$

then,

$= > \frac{5 \times 3}{2 \times 4}$

$= > \frac{15}{8}$

In the same way ,

$= > \frac{ \frac{1}{1} }{ \frac{60+1}{30} }$

$= > \frac{30}{60+1}$

hope it help to understand!

Answer 2

Answer:

⇒

      1

-----------------

10     +        1

            --------------

               60+1

              ---------

                  30

This 30 is Denominator  of (60+1) part so in next step it will up with 1 and multiply there with 1 to becomes 30.
