Question

9.1 times 11.8 estimate the product by rounding each decimal number to the nearest whole number

Answer 1

Rounding up---9.1 to 9 and 11.8 to 12
So, their product is 9*12=108

Answer 2

We will round both numbers:-

9.1 = 9 

11.8 = 12

Now we will multiply these 2 numbers to get our answer. 

9 × 12 = 108

So, 9.1 ÷ 11.8 is ABOUT 108.
