100x = 21.212121.....
100x - x = 21.212121... – 0.212121...
99x = 21. ( divide both side by 90)
x = 21/99
x = 21:3/99:3
x = 7/33

3. Let's use pemdas
1/2 * 24 / 3 +2
12 / 3 +2
4 +2
=6
4. Let's use pemdas
2 * (6 / 2 + 8) -4
2 * 11 - 4
22 - 4
= 18
5. Let's use pemdas
(28 / 7 +6 / 3) * 1/2
( 4 + 2) *1/2
