Round 3.06735995694 to the nearest millionth.

The "th" family is a little confusing but you look and find the millionth place. It's basically backwards.

0 is tenths

6 is hundredths

7 is thousandths

3 is ten-thousandths

5 is hundred-thousands

9 is millionths

the number next to it is a 9 (rule round up if it's greater than 5)

since the number is a 9 you have to round up even one more making the 5 a 6
