If the tiger has consumed 72 pounds of food in 6 days that's \( \frac{72}{6} \) = 12 pounds of food per day. The tiger needs to consume 156 - 72 = 84 more pounds of food to reach 156 pounds total. At 12 pounds of food per day that's \( \frac{84}{12} \) = 7 more days.

To multiply fractions, multiply the numerators together and then multiply the denominators together:

\( \frac{1}{8} \) x \( \frac{4}{8} \) = \( \frac{1 x 4}{8 x 8} \) = \( \frac{4}{64} \) = \(\frac{1}{16}\)

The commutative property states that, when adding or multiplying numbers, the order in which they're added or multiplied does not matter. For example, 3 + 4 and 4 + 3 give the same result, as do 3 x 4 and 4 x 3.

There are 3 2-passenger taxis available so that's 3 x 2 = 6 total seats. There are 8 people needing transportation leaving 8 - 6 = 2 who will have to find other transportation.

To subtract these fractions, first find the lowest common multiple of their denominators. The first few multiples of 4 are [4, 8, 12, 16, 20, 24, 28, 32, 36, 40] and the first few multiples of 6 are [6, 12, 18, 24, 30, 36, 42, 48, 54, 60]. The first few multiples they share are [12, 24, 36, 48, 60] making 12 the smallest multiple 4 and 6 share.

Next, convert the fractions so each denominator equals the lowest common multiple:

\( \frac{7 x 3}{4 x 3} \) - \( \frac{7 x 2}{6 x 2} \)

\( \frac{21}{12} \) - \( \frac{14}{12} \)

Now, because the fractions share a common denominator, you can subtract them:

\( \frac{21 - 14}{12} \) = \( \frac{7}{12} \) = \(\frac{7}{12}\)
