A bread recipe calls for 2 cups of flour. If you only have 1\(\frac{1}{2}\) cups, how much more flour is needed?
| 2\(\frac{3}{8}\) cups | |
| \(\frac{3}{4}\) cups | |
| 1 cups | |
| \(\frac{1}{2}\) cups |
The amount of flour you need is (2 - 1\(\frac{1}{2}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{16}{8} \) - \( \frac{12}{8} \)) cups
\( \frac{4}{8} \) cups
\(\frac{1}{2}\) cups
Which of the following is a mixed number?
\({5 \over 7} \) |
|
\(1 {2 \over 5} \) |
|
\({a \over 5} \) |
|
\({7 \over 5} \) |
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.

There are 3 2-passenger taxis available so that's 3 x 2 = 6 total seats. There are 10 people needing transportation leaving 10 - 6 = 4 who will have to find other transportation.
4! = ?
3 x 2 x 1 |
|
4 x 3 |
|
4 x 3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
