(80) / (1/4) = 320
The pattern in the sequence 320, 160, 80, 40 is that each number is being divided by 2 to obtain the next number. Specifically, 320 divided by 2 equals 160, 160 divided by 2 equals 80, and 80 divided by 2 equals 40. This creates a geometric sequence where each term is half of the previous term.
80 - 320 = -240
320 of 80 = 25600
80
80 (240/80 = 3 and 320/80 = 4)
320.
80/0.25 = (4*80)/(4*0.25)=320/1=320
80 + 80 + 80 + 80 = 320 millilitres.
80 / 0.25 = 320 Therefore, 80 is 25 percent of 320.
