What is 3 1/8 - 1/2
irina1246 [14]

Answer:

\frac{21}{8}

Step-by-step explanation:

Given: 3\frac{1}{8} - \frac{1}{2}

Let's changed that mixed number to an improper fraction. Now we get:

\frac{25}{8} - \frac{1}{2}

Let's find out least common denominator. This one is easy, the LCD is 8. Now that we know the LCD, let's convert both our fractions:

\frac{25}{8} - \frac{4}{8}

We can use \frac{4}{8} because it is equal to \frac{1}{2}. Now, all we need to do is subtract the numerators:

\frac{25}{8} - \frac{4}{8}=\frac{21}{8}
