Round 0.683 to the nearest tenth. a.0.7 b.0.68 c.1.0 d.0.6

A. 0.7

Step-by-step explanation:

If you look at your original decimal 0.683, to round to the nearest tenth you would look at the second digit that comes after the decimal so in this case the underlined one 0.683.  If that second digit is 5 or greater, which it is, then you would round up to the next highest number from the 1st digit after the decimal, so in this case 7 :)
