How to round 70 to the nerest 100

den301095 [7]

Answer:

100

Step-by-step explanation:

First, you look at wether the first digit in this case is above or below a 5. Since it is, you would round up. The closest hundred to this number is 100, so that is the answer. For 3 digit numbers or higher, look at the tens place to determine the nearest hundred. Same rule applies for rounding up or down.

Hope I helped :)
