Question

Deshawn fuels 2 yachts and 6 barges. Each boat gets 126 gallons of fuel. To find how much fuel he needs for all the boats, deshawn first findsthe number of boats, then he uses an algorithm to multiply. Which are the three partial products deshawn could add to find the final product?

Answer 1

The total number of boats is given by 2 + 6 = 8

Thus, the amount of fuel he needs for all the boats is given by 8 x 126

Using place value system and extended number system, we have:

$8\times126=8\times100+8\times20+8\times6 \\ \\ =800+160+48=1,008$

Therefore, the three partial products deshawn could add to find the final product are 800 + 160 + 48
