Is 0.2 bigger than 0.15

Well we compared two decimal numbers and found that 0.2 is greater than 0.15. Some students would argue that 0.15 is a longer decimal with more digits, and is therefore greater than 0.2. But they are wrong.

0.2 can be put as: 1/5 (as a fraction) 20% (as a percent)

0.15 can be put as: 3/20 (asa fraction) 15% (as a percent)

Yes it is because 0.2 can also be written 0.20 which is bigger than 0.15
