Answer:

900

Explanation:

You are given the proportion


x:81=27:2.43

Rewrite it in fraction form:


(x)/(81)=(27)/(2.43)

Cross multiply:


2.43\cdot x=81\cdot 27

Divide by 2.43:


x=(81\cdot 27)/(2.43)\\ \\x=(81\cdot 27)/(9\cdot 0.27)\\ \\x=(9\cdot 27)/(0.27)\\ \\x=(9\cdot 2,700)/(27)\\ \\x=(9\cdot 100)/(1)\\ \\x=900
