Answer:
Aaron needs 2 more rolls to complete the path.
Step-by-step explanation:
Given:
Total rolls Aaron has = 4
Part of path covered by using [tex]\frac{3}{4}[/tex] of a roll = [tex]\frac{1}{8}[/tex]
So, in order to find the number of rolls required to cover the complete path is given using the unitary method.
Rolls used for [tex]\frac{1}{8}[/tex] of a path = [tex]\frac{3}{4}[/tex]
Therefore, rolls used to cover the whole path is given by dividing the rolls used for one-eighth of the path and the path covered. This gives,
[tex]=\frac{3}{4}\div \frac{1}{8}[/tex]
[tex]=\frac{3}{4}\times \frac{8}{1}[/tex]
[tex]=\frac{3\times 8}{4\times 1}[/tex]
[tex]=\frac{24}{4}[/tex]
[tex]=6\ rolls[/tex]
Now, rolls required to complete the path is 6. But Aaron has only 4 rolls.
So, he will need 6 - 4 = 2 rolls more to complete the path.
