Question

How do you convert 2/7 into a decimal and percent?

Answer 1

`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.

Answer 2

`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...%`
