7+11=18
18 and 1/2 is answer or 37/2 or 18.5
Answer: 80%
Step-by-step explanation:
40/50 = 80/100 = .8 then move decimal over 2 places to the right for percent. .8 to 8.0 to 80.0
First you turn 20% into a decimal by dividing by 100 and you get .20
then you multiply .20 by 160 and get 32
then subtract:
160-32=128
So if you have 120 bananas and you have a 20% decrease then you would have 128 left over
Hope this helped!! :D
If you take 90 x 7/8 you get 78.75 min. That's how long he was doing flip tricks. To find the time he's been doing slides, you take the total time (90) minus the amount of flips (78.75) and you get 90-78.75 and the answer is 11.25. If this helped please hit the thanks button :)
