80% of 80 is 64 64 right answers right and 16 wrong answers
There can be no GCM (Greatest Common Multiple). Suppose a GCM exists and suppose it is x. That is, x is the GCM of 7 and 13, then 2x is a multiple of both 7 and 13 and is greater than x. This contradicts the statement that x is the GCM. So x cannot be the GCM.
64+16 = 80
The greatest common multiple of any set of integers is infinite.
64/80 = 8/10 = 80/100 = 80% 64 is 80% of 80.
64% of 80 = 80*64/100 = 51.2
100*64/80 = 80%
The greatest common multiple of any set of integers is infinite.
The number 80 means 100 percent 80/100 = 0.8 means 1 percent. 64/0.8 gives 80 percent, belonging to the number 64.
(64 + 80)/2 = 72
The Least Common Multiple (LCM) of 64 and 80 is 320.
The decrease from 80 to 64: 20%
20% of 80 is 16 and 80-16= 64
125% of 64= 125% * 64= 1.25 * 64= 80
25% 80-64 = 16 16/64 = 1/4
