Answer :
To divide fraction by number we can multiply fraction by inverse of number.
Lets find inverse
21=[tex] \frac{21}{1} [/tex] =====> [tex] \frac{1}{21} [/tex] - its inverse of 21
Now we can multiply it
[tex] \frac{9}{49}* \frac{1}{21}= \frac{9*1}{49*21} = \frac{9}{1029}= \frac{9:3}{1029}= \frac{3}{343} [/tex] - its our result

9/49 divided by 21 to solve this make the 21 a fraction by placing it over 1
9/49 divided by 21/1 the use the reciprocal of 21/1
9/49 divided by 1/21 then multiply across
9*1= 9
49*21=1029
then simplify
9/3 = 3
1029/3 = 343
so 3/343 is the answer
