Answer:
Step-by-step explanation:
1) let x = 0.555 ------ (i)
10 x = 5.555 -------(ii)
Subtract eqn. (i) from (ii)
10x - x = 5.555 - 0.555
9x = 5
x = 5/9
2) let x = 0.3222 ------ (i)
10 x = 3.2222 -------(ii)
100x = 32.2222 --------(iii)
Subtract eqn. (ii) from (iii)
100x - 10x = 32.2222 - 3.2222
90x = 29
x = 29/90
3) let x = 0.266 ------ (i)
10 x = 2.666 -------(ii)
100x = 26.666 -------------(iii)
Subtract eqn. (ii) from (iii)
100x - 10x = 26.666 - 2.666
90x = 24
x = 24/90 = 12/45 = 4/15
4) let x = 0.333 ------ (i)
10 x = 3.333 -------(ii)
Subtract eqn. (i) from (ii)
10x - x = 3.333 - 0.333
9x = 3
x = 3/9 = 1/3
