How many time can you subtract2.5 from 30 until you get 0
Once! After you have subtracted it once, you are subtracting 100 from 1900, and then 100 from 1800 and on and on
100/5 = 20
-20
5 goes into 100 20 times
How many time can you subtract2.5 from 30 until you get 0
Once! After you have subtracted it once, you are subtracting 100 from 1900, and then 100 from 1800 and on and on
2000/20 = 100 20 goes into 2000 by 100 times.
100/5 = 20
-20
5 goes into 100 20 times
20
Exactly 20 times
20 times with 4 remaining 104 - 4 = 100 100 / 5 = 20
20 times
Take 20% of the original amount and subtract it from the original amount. For example: 100 - 20% 100 - (0.20*100) = 100 - 20 = 80 An easier way to do the same problem is to know that if you subtract 20% from something then there will only be 80% of the original amount left (100% - 20%). So in the previous example take 80% of the original amount to get the same answer. 80% of 100 = 0.80 * 100 = 80
20 goes into 100 five times.
