Answer: the tax is $2.16 so total would be $74.16 if the original ticket price was $72.00
Step-by-step explanation:
T + 0.03
T = 72
72 • 0.03 = 2.16
72 + 2.16 = 74.16
$74.16
Casserole left over by Sam = 3/4 of the whole
Casserole received by Jackie and Alicie = 1/2 x 3/4 = 3/8 of the whole
Portion eaten by Jackie = 2/3 x 3/8 = 1/4 of the whole
You are finding 3 1/6 - 1 5/6.
To solve, you should first change it so that the numerator of the first fraction is greater than the numerator of the second. Note that both have the same denominator (6). Subtract as usual:
3 1/6 = 2 7/6
2 7/6 - 1 5/6 = 1 2/6
1 2/6 is your answer.

Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.
