Question

sam used 6 loaves of elf bread on an 8 day hiking trip. he wants to know how many loaves of elf bread (b) he should pack for a 12 day hiking trip if he eats the same amount of bread each day.

Answer 1

loaves:days=6:8
6/8=3/4
3/4=x/12
find x
3/4=x/12
times 12 both sides
36/4=x
9=x
answer is 9 loaves

Answer 2

He should pack 9 loaves of bread for a 12 day hiking trip if he eats the same amount of bread each day.

Explanation:

Hint- This can be solved by Unitary method.

Sam used 6 loaves of elf bread on an 8 day hiking trip.

or in an 8 days trip he used 6 loaves of bread,

so in 1 day he would use
`(6)/(8)` loaves of bread,

so in a trip of 12 days he would use
`(6)/(8)* 12=9` loaves of bread.

Therefore, he should pack 9 loaves of bread for a 12 day hiking trip if he eats the same amount of bread each day.
