S + a = 722
s = 72 + a
(72 + a) + a = 722
2a + 72 = 722
2a = 722 - 72
2a = 650
a = 650/2
a = 325 <== adults
s = 72 + a
s = 72 + 325
s = 397 <== students
It is b

She simplified it wrong because you're only supposed to simplify it with the same numbers. For example: simplify 2/4. You divide it by 2/2. You do the same and it will be correct.

Answer:
(A) 1/8 x 1/6
Step-by-step explanation:
Division by a number (or fraction) is the same as multiplication by its reciprocal. That is, division by 6 is the same as multiplication by 1/6.
(1/8) ÷ 6 = 1/8 × 1/6
__
<em>Additional comment</em>
The original division problem can also be formulated as ...
(1/8) ÷ (6/1) . . . . . matches choice D
In order to do this division, you would typically rewrite this to 1/8 × 1/6 (choice A).
