9. \( 5+\frac{1}{4}= \)

To solve \( 5 + \frac{1}{4} \), you can think of it as adding a whole number to a fraction. Since 5 can be expressed as \( \frac{20}{4} \) (by multiplying both the numerator and denominator of \( \frac{1}{4} \) by 5), this gives us \( \frac{20}{4} + \frac{1}{4} = \frac{21}{4} \), which simplifies to \( 5.25 \) or \( 5\frac{1}{4} \). Here's a fun way to remember fractions: Picture a pizza divided into four equal slices. If you have one slice (that’s \(\frac{1}{4}\)), and you stack it on top of a whole pizza, you’ve got 5 pizzas and a slice—so, that's a feast of \( 5\frac{1}{4} \) pizzas ready to serve!
