Question

Sam used 6 loaves of elf bread on a 8 day hiking trip. He wants to know how many loaves of elf bread he should pack for a 12 day hiking trip if he eats the same amount every day.

Answer 1

If he eats 6 loaves in 8 days, that means he ate 0.75 of a loaf each day. (6 divided by 8 = 0.75)
In a 12 day trip,
# divided by 12 = 0.75;
so to undo division, you multiply.
12 x 0.75 = #
# = 9. So 9 loaves for 12 days.
