A tiger in a zoo has consumed 36 pounds of food in 6 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 72 pounds?
| 9 | |
| 11 | |
| 8 | |
| 6 |
If the tiger has consumed 36 pounds of food in 6 days that's \( \frac{36}{6} \) = 6 pounds of food per day. The tiger needs to consume 72 - 36 = 36 more pounds of food to reach 72 pounds total. At 6 pounds of food per day that's \( \frac{36}{6} \) = 6 more days.

There are 2 5-passenger taxis available so that's 2 x 5 = 10 total seats. There are 12 people needing transportation leaving 12 - 10 = 2 who will have to find other transportation.
Which of the following is an improper fraction?
\(1 {2 \over 5} \) |
|
\({7 \over 5} \) |
|
\({2 \over 5} \) |
|
\({a \over 5} \) |
A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.
A bread recipe calls for 3 cups of flour. If you only have 1 cup, how much more flour is needed?
| 1\(\frac{3}{8}\) cups | |
| 2 cups | |
| 1\(\frac{1}{2}\) cups | |
| 2\(\frac{1}{8}\) cups |
The amount of flour you need is (3 - 1) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{24}{8} \) - \( \frac{8}{8} \)) cups
\( \frac{16}{8} \) cups
2 cups
