Answer:
[tex]\displaystyle 8[/tex]
Step-by-step explanation:
List all the factors of twenty-seven, then sum them up:
[tex]\displaystyle 1, 3, 9, 27; 40 = 27 + 3 + 9 + 1[/tex]
Now, the clue tells you that forty is the fifth multiple of some quantity, so divide by five to get your result, and it MUST be a whole number, or elce we have no solution here:
[tex]\displaystyle 8 = \frac{40}{5}[/tex]
Eight is the quantity you are looking for, and sinse it is a whole number, it is valid.
