Question

Estimated to the nearest hundredth, 12.581 + 15.685

Answer 1

To find this estimation, we can begin by simply adding the numbers:

12.581 + 15.685 = 28.266

Now, we can round according to the digit two places to the right of the decimal point, more commonly known as the hundredths place.

Because there is a 6 to the right of the hundredths place, we round the hundredths digit (6) up to 7. The number then becomes 28.27.

Hence, estimated to the nearest hundredth, 12.581 + 15.685 = 28.27.
