We want to find relationships between $27 and $81.
1.
Note that 81/27 = 3
Therefore
$81 = 3($27)
2.
Note that 81 = 27 + 54
Therefore
$81 = $27 + $54
3.
Note that $27 = $81/3
Therefore
$27 = (1/3)$81
Answer:
The three relationships are
(1) $81 is three times $27.
(2) $81 is $27 plus $54.
(3) $27 is one-third of $81.
