Help umm how do i do this im dumb idk how to do it :(

WITH DECIMAL: the bigger the demominateor (the bottom number) is, the smaller the value of the number. for ex. 1/4 is smaller then 1/2, 1/8 is bigger then 1/16, etc.

1/4 would go in between 0 and -1 because 1/4 isn't a whole number

-3 1/4 would go in between -3 and -4 becauce 3 AND 1/2 is more then just a 3

-2 3/4 would go in between -2 and -3 becasue 2 + other 3/4 is going to be bigger than 2 but smaller than a 3

9/4 is a tricky one casue 9 is bigger then 4. so you need to see how many times 4 goes into 9 (2 times = 4 +4 = 8) so the simplfied version would be 2 1/4 casue 9 - 8 = 1. so the 9/4 would go in between 2 and 3

lastly, the 3/4 would go in between 0 and 1 becasue 3/4 is deffinately smaller than 1 and definatly bigger than 0

( are greatly appershated, commnet for help!)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
