Answer:

348.8745 --> 348.87

35.86 --> 35.86

$42.19 --> $42

158.097 --> 158.1

Step-by-step explanation:

If the number after the number we are rounding to is less than or equal to 4, we round down.

Ex : 123.454 to the nearest hundredths is 123.45 because the 4 in the thousandths place is equal to 4.

If the number after the number we are rounding to is greater than or equal to 5, we round up.

Ex : 123.456 to the nearest hundredths is 123.46 because the 6 in the thousandths place is greater than 6.
