Answer 1

Solution:

Let the required number x/y

Now, ratio of 8/21 to 4/9  = $\frac{8/21}{4/9}$= 8/21×9/4=6/7

Thus, we have

$\frac{x/y}{7/33}$ = 6/7

=> x/y = $\frac{6/7}{7/33}$

=> x/y = 6/7 × 7/33

=> x/y = 2/11

Hence, the required number is 2/11.

Answer 2

Answer:

Solution:

Let the required number x/y

Now, ratio of 8/21 to 4/9 =

$\frac{8/21}{4/9}$

= 8/21×9/4=6/7

Thus, we have

$\frac{x/y}{7/33} </p><p>$

= 6/7

=> x/y =

$\frac{6/7}{7/33}$

=> x/y = 6/7 × 7/33

=> x/y = 2/11

Hence, the required number is 2/11.
