0.29 and 28.6%

Explanation:

You use a calculator, use 2, /, 7 as the input, and then you got a long decimal as 0.285714286.... However, you can round it up usually to two decimal places, or if there is an order, go for that order.

For percentage, just simply move the "." to the right for two space, and then round it, and then add the % sign.

0.\bar{285714} = 28.\bar{571428}%

Explanation:

Divide 2 by 7:

2 = 0 * 7 + 2 // remainder 2

20 = 2 * 7 + 6

60 = 8 * 7 + 4

40 = 5 * 7 + 5

50 = 7 * 7 + 1

10 = 1 * 7 + 3

30 = 4 * 7 + 2 // remainder 2 repeats

2/7 = 0.\bar{285714} = 0.285714285714285714...

(200%)/7 = 28.\bar{571428}% = 28.571428571428571428...%
