The answer is ONE (1). If you have one-fifth, and multiply it by two, you have two fifths.Five fifths is exactly the same as ONE (1).
one twentieth 1 / 5 x 1 / 4 = (1 x 1) / (5 x 4) = 1 /20
one fifth of 100000 = 1/5 x 100000= 100000 ÷ 5= 50000
x5-1 = (x - 1)(x4 + x3 + x2 + 1)
1/5 x 1/2 = 1/10 (one tenth)
1/5 x 1/3 = 1/15
1/2 x 1/5 is 1/10
One fifth of six is 6/5 = 1.2
One-tenth of 750 = 75 One-fifth of 75 = 15 One-third of 15 = 5 OR 750 x 1/10 x 1/5 x 1/3 = 750/150 = 5
1/5 x 100 = 20
1/5 x 60 = 12
1/5-0.2
