I did this in my head .021 is larger I went with 1/50 = 2/100 = 20/ 1000 So one can see where I am going here
I didn’t have calculators when I went to high school 72 - 76
.021 in less than two seconds in my head. This is a nice problem for working with scale of place numbers. My son is learning this: '=', ''. Nice video! To me, this was simply a case of 1/5 = 0.2, which was nearly an instantaneous fact recall. From there, 1/50 = 0.02; hence, 0.02 < 0.021, et voilà!
His objective by teaching us to do problems with pencil and paper is to prepare students for problems that cannot easily be done in your head.
1/50 = .02, so .021 is larger
Decimal greater>
.021 is larger
.021 > 1/50.
.021
50÷1=0.020
50/1=50. Cheers
