Answer 2

Answer:

Step-by-step explanation:

1-14.256

he question has a total of three decimal places. so,we have to put the decimal point three places to the left.

2- Given If, 503 × 217 = 109151, then 5.03 × 2.17 = ?

So if we multiply

5.03 x 2.17   we get

------------------

      3521

      503

  1006

--------------------

10.9151  

So we can keep the point after four places.

So we can do it in one more method which is

503 / 100 x 217 / 100 By removing the point

We get 109151 / 10000

Now after dividing we get  10.9151 which is the required answer
