### Example Question #1 : Mixed / Improper Fractions

Write as an improper fraction.

**Possible Answers:**

**Correct answer:**

To find the improper fraction value, we must effectively add together 71 and ^{5}/_{7}. To do this, we will give 71 a denominator of 7; therefore, we are transforming ^{71}/_{1} to ^{x}/_{7}. The shortest way to do this is to multiply by ^{7}/_{7} (which really is 1); therefore, 71 = 71 * (^{7}/_{7}) = ^{497}/_{7}.

Now add them: ^{(497 + 5)}/_{7} = ^{502}/_{7}
