Question

What is 1.6 * 0.9? estimate and correct answer

Answer 1

The awnser to 1.6 is 2 because 6 is greater than 5,and the awnser to 0.9 is 1 because 9 is greater than 5,but don't get me wrong if it was 5 it will still round up it just cant be less than 5,because if less than 5 it stays the same.

Answer 2

1.6 is close to 1.5
0.9 is close to 1
So, multiple 1.5 and 1
1.5 * 1 = 1.5
1.5 is the estimated answer.

Correct answer
1.6 * 0.9 = 1.44
