Answer:
B) 1/5 and D) 0.20
Explanation:
20% in calculating is 0.2. Anything that equals 0.2 is equal to 20% in your calculator.
A is already a decimal so theres no need to calculate. Sure it has 0.2 but it also has a 5. (0.25) which would equal 25%. Not 20%.
C is not a decimal, so you'll have to calculate. (the symbol "/" means ÷ or divide.) So just divide 1 ÷ 10. It's 0.1 or 10%. it isnt 0.2 so that is also incorrect.
B is the same as C. just divide and calculate. 1 ÷ 5 = 0.2 (20%) Which is 20% So B is correct.
D. Yes it has a 0.2 but also a 0. But always remember. If there is no 0 in front of the number, OR if there is no number BEHIND the 0, it's invisible. For example: 0.10000000000000000000000000 is basically 0.1 because its behind. now if it was 0.01000 just 0.01 and if it was 0.0123 it would be 0.0123. because of those digits.
