Answer 2

Answer:

2.8 * 3.9 = 10.92

2.8 * 0.39 = 1.092

Step-by-step explanation:

For 2.8 * 3.9 write down 1092.

Now, there are total two decimal places (one in 2.8 and one in 3.9) so counting from left, give a point after  two places. So you get 10.92.

Similarly, for 2.8 * 0.39 give three places, and you get answer 1.092
