Answer:31 dived by 81 is 0.3703
Step-by-step explanation:
I would make both denominators the same, and the lowest one that works is 18. So I'd make 1/9 into 2/18, and 1/6 into 3/18. They already used these times so combine them to make 5/18 then subtract that from the total time they had (18/18) and you would get 13/18 they spent playing music.
Answer: 3x^2 +120x
Good luck !
22/100:
You can actually divided the numerator and denominator by a number that can go into both 22 and 100 but also not get a remainder.
So 22/2= 11
And 100/2=50
Combined you get 11/50
Hope it helps!!!
