2/10< 0.02 is thuis this correct because i need and i'm working on this all day is this correct

One way of figuring out which is greater is by turning both number into decimals

2/10 is the same as saying 2 ÷ 10 
if you do 2÷10 you should get
0.2
0.2 is closer to 1 than 0.02 so
0.2 > 0.02
2/10 > 0.02

another way would be to turn both into fractions
0.02 is said as "two thousandths" so it can be written as it is said
2/1000
2/1000 is much smaller than 2/10 so
2/10 > 0.02

hope this helped!
