Answer 1

Answer:

$12.87 \times 4.2$

$=$

$54.054$

Answer 2

Answer:

54.054

Step-by-step explanation:

Let's ignore the point

1287*42

2574 ( multiply 2 to 1287)

5148x ( multiply 4 to 1287)

54056

The answer is 54056

Now place point after 3 digits from right side because we have 3 ( 2+1 ) digits after point in the question. That is 54.056
