Question

7.2/x = 0.25 /1 1/9

Answer 1

`(7.2)/(x)= (0.25)/(1 (1)/(9) )`
Solving for x.
First convert the mix number into improper fraction.

`1 (1)/(9)= (10)/(9)`

`As \ (a)/((b)/(c)) = (ac)/(b) \\`
We get

`(7.2)/(x)= (0.25* 9)/(10) \\ (7.2)/(x)= (2.25)/(10) \\ 2.25x=7.2 * 10 \\ 2.25x=72\\ x=32`

Answer: x=32
