Question

round 3.178 to the nearest hundredth

Answer 1

Answer:

3.18

Step-by-step explanation:

In this number, the 7 is in the hundredths place. All we are doing is simply rounding the whole number to this place number. We know that in order to round a number up or down we must know the preceding number (in this case 8, which is in the thousandths place, precedes our hundredths place number; 7). Since 8 is greater than 5, we can round our hundredths place number up by one unit. So in the end we get not 3.178, but instead 3.18.

Answer 2

Answer:

3.2

Step-by-step explanation:

3.178: Hundredths place is 7

Decide if it's less than 5 or greater than 5.

If it is less than 5 then it will turn to zero and the numbers after it will also be zero. If it is more than 5 it will be zero and the number before it will increase by 1.

Since it is more than 5 the number it will turn to zero and the number before it will increase by 1. So it will be 3.200 or 3.2.
