Hi
There is more than one answer for this.1 x 80 = 802 x 40 = 804 x 20 = 805 x 16 = 808 x 10 = 805 (calculator told me)
80 cm is less.
80
80% less than 90 = 20% of 90 = 18
-56
80 is smaller than 666.
In between .8 and .81 we find .805 (and infinitely many other numbers).
It is 80 fewer than or 80 less than some previously specified value.
80 - 15 = 65
less than 80 centimeters is equal to .8 meter and therefore .8m is less than 8m
80-80*20%=64
