Answer 2

Answer:

18

Step-by-step explanation:

the equation formed will be

4 : x : : x : 9

( continuous proportion means that particular number is coming twice)

so now they will be cross multiply

4×9 = x×x

here we will multiply extreme terms together and mean terms together

it will be now

36 = 2x

which can also be written as

2x = 36

after this the "x" will remain there and 2 will come on other side

x = 36/2

( 2 was in multiply so when it will go to other side it will come in divide )

36 divide by 2 will be 18

so our answer will be 18

4 : 18 : : 18 : 9
