Final answer:
0.697 rounds up to 0.70 when rounded to the nearest hundredth because the third decimal digit (7) is greater than 5.
Step-by-step explanation:
To round 0.697 to the nearest hundredth, we look at the third decimal place, which is 7. Since 7 is greater than 5, we round up the second decimal place from 9 to 10. However, since there is no digit '10' in a single decimal place, we increase the first decimal place by 1 and reset the second place to 0. Therefore, the number 0.697 rounded to the nearest hundredth is 0.70.
