40+80=120. 40/120=.3333.... or 1/3. so sandwiches percent is 33% and so 100-33= 67 so the bottles of water would be 67%
The answer is 30. you can find the unit rate but the calculator was invented a long time ago so i used that ;)
Divide both numbers by 20
20/20 and 100/20= 1/5
So 1/5 is the answer
5/8 - 5/12 ( 3 - 1/4 ) + 2/3=5/8-5/12*11/4+2/3=5/8-55/48+2/3=7/48
