Estimate by rounding. Show how you estimated.

OPTION 1: 200 x 6 = 1200
OPTION 2: 220 x 6 = 1320
OPTION 3: 210 x 6 = 1260
OPTION 4: 230 x 6 = 1380

Answer 1

To estimate the product of 218 and 6, round both numbers to the nearest tens place. Option 3, 210 x 6 = 1260, is the closest estimate.

Step-by-step explanation:

To estimate the product of 218 and 6, you can round both numbers to the nearest tens place.

Option 3, 210 x 6 = 1260, is the closest estimate because 218 is closer to 210 than it is to 200 or 220.

To round 218 to the nearest tens place, look at the ones digit.

Since it is greater than or equal to 5, you round up to the next tens place, which is 220.

To find the product, you simply multiply 220 by 6, resulting in 1320.
