Jamie has a half-sheet cake. If she has six friends, how much will each one get?

sesenic [268]

Answer:

<h2>The answer is </h2><h2>B. 1/12</h2>

Step-by-step explanation:

step one:

From the problem state, we can actually conclude that Jamie wants to share the half sheet of cake among her 6 friends

step two:

we can express this problem mathematically as

$=\frac{1}{\frac{2}{6} }$

we can inverse the denominator and use a multiplication sign instead

$\\\\= \frac{1}{2}*\frac{1}{6}$

multiplying both denominators we have

$\\\\= \frac{1}{12}$

The answer is B 1/12
