Question

1.248 x 400
= 2899.200
Or
7248 x 400 - 2899200
Multiply mentally first by 4 and then by
100. Put decimal point after 3 places,
7.248 x 400 = 2899.200
2899.2

3 places
0.3506
x 0. 138
28048
10518
3506
0.0483828
Since the product 483828 contains fewer digits than the required
number of decimal places, we add one zero on the left of the
number so that the product may have the necessary seven
decimal places.
7 places (4 + 3 = 7)
Add this O to make 7 places
