6- Choice C is correct
The correct answer is \(\frac{1}{4}\) To compare fractions, we can write fractions with the same denominator. Then, we can compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least. Common denominator of \(2,\ 3,\ 4\) and \(12\) is \(12\). Rewrite the fractions: A. \(\frac{5}{2}\ =\ \frac{30}{12}\) B. \(\frac{2}{3}\ =\ \frac{8}{12}\) C. \(\frac{1}{4}\ =\ \frac{3}{12}\) D. \(\frac{9}{12}\) Therefore, \(\frac{3}{12}\) or \(\frac{1}{4}\), choice C, has the least value.

|
27- Choice D is correct
The correct answer is \(416\) minutes Each game = \(1\frac {1}{2}\) hours = \(90\) minutes, therefore \(4\) games took \(6\) hours = \(360\) minutes. \(7\) minutes between each game. There are \(21\) minutes in total between \(4\) games. (between game \(1\) and \(2\), \(7\) minutes and between game \(2\) and \(3\), \(7\) minutes and between game \(3\) and \(4 \), \(7\) minutes ) Lily arrives \(20\) minutes before first game and left \(15\) minutes after the last game. In total, she was \(360\ +\ 21\ +\ 20\ +\ 15\ =\ 416\) minutes at the soccer field.
