There is more than one answer for this.
1 x 80 = 80
2 x 40 = 80
4 x 20 = 80
5 x 16 = 80
8 x 10 = 80
5 (calculator told me)
80
80/A
90 times 80 = 7200
53 times 80 equals 4240.
720/80 = 9
It equals: 7,200
240 feet equals 80 yards, because 3 feet equals 1 yard. 80 times 3 equals 240. (8 times 3 equals 24, and you just add a zero.)
4 x 20 = 80
80 times 0.55 equals 44
30 x 80 = 2400
5.33333333333333 x 15 = 80
1 times -80 is one possible answer.
