Anyone good with fractions? ? all i need is someone to explain how to get the answer to this problem. i can't figure it out.

Don’t worry! Fractions aren’t my thing either but here’s how to solve it:

First do 54 1/3 - 15 2/3 = 38 2/3. Then do 38 2/3 divided by 3 1/3 = 11 3/5. Rounded, Olivia will spend 11 day. Hope this helps!!

The complete question in the attached figure

we know that
(20/34)=16/x----------> 20*x=34*16

therefore
case 1)34/x = 20/16------> 34*16=x*20-------> this proportion is correct
case 2)16/20 = x/34------> 16*34=20*x-------> this proportion is correct
case 3)20/16 = x/34------> 20*34=16*x------>  this proportion is not correct
case 4)20/16 = 34/x-------> 20*x=16*34-------> this proportion is correct

the answer is
the proportion can be used to find the distance x are
1)34/x = 20/16
2)16/20 = x/34
4)20/16 = 34/x
