15. Estimate the product of 110.4 x 10.2 by rounding to the nearest whole number. A.1100
B.1210
C.1000
D.1221

A.1100

Step-by-step explanation:

Hi, to answer this question we have to round each number to the nearest whole number:

110.4 = 110 (.4 is less than 5)

10.2 = 10

The product is the result of the multiplication of both numbers:

110 x 10 = 1,100

So, the correct option is A.1100
