Question

Deshawn fuels 2 yachts and 6 barges.

Answer 1

The number of boats are 8; so, he needs a total of 8*126 gallons.

In order to get the partial products, first you have to decompose 126 in its hundreds, tens and ones, that is, 126 = 100 + 20 + 6. Then multiply each of this terms by 8, as follows

8*100 = 800

8*20 = 160

8*6 = 48

Finally you have to add the results of these multiplications, that is, 800 + 160 + 48 = 1008. Therefore, he needs 1008 gallons for all the boats.
