Note that we are estimating, not finding the actual value. 0.499 is very close to 0.5, so to estimate this expression, we can do 196 ÷ 0.5. Dividing a number by 0.5 is the same as doubling it, so this can also be seen as 196 · 2, which is 392.
Hope this helps !! :D The actual answer is the other one, but again, you're finding an estimate!
~ The technique of dividing a quantities into equivalent portions as well as determining however many equal components may be formed, is determined as a division.
