is 0.21 less or greater than half
less than half because .5 is half of one
.5 = .50
compare the 2. that's what I do.
.50
.21
forget the decimal. and pretend that 100 = 1
Hope this helped
0.21 is less than half because a half is 0.5. So 0.21 is less than 0.5 because the tenths place is less than 5 which makes 0.21 smaller than a half
