Which answer expresses the ratio as a fraction in simplest form? 18: 24 1/2 2/3 6/7 3/4

First we need to find the gcf (greatest common factor) of 18 and 24

in this case it would be 6, since it’s the highest number you can divide both 18 and 24 by without leaving you with a remainder

then we divide both 18 and 24 by 6, leaving you with 3/4

hope i helped!

The amount used= 13.04- 1.9 = 11.14
