4/10 can be simplified to 2/5. 1/5 is equal to 20% (you probably want to memorize that) so all you have to do is multiply 20% by 2 (because of the numerator) and get 40%
So therefore 4/10 = 2/5 or 40%
P.S if you have anything over ten that needs to be a percent just multiply 10% by the numerator.
Answer:
there is no expression
Step-by-step explanation:
what are you talking about
The first chain is 5 because 17-13 equals 4 and 9-4 equals 5 so that's the answer
Your answer is 30 bags, if you do 18/3=6 then 5*6=30
