Solve the Fraction Equation: Finding the Missing Number in ?+2/8=3/4

Simplifying $\frac{2}{8}$ to $\frac{1}{4}$ makes the problem much easier! Both fractions will have the same denominator (4), so you can work with the numerators directly.

Think of it like this: "What plus $\frac{1}{4}$ equals $\frac{3}{4}$?" To find the missing piece, subtract the known part from the total: $\frac{3}{4} - \frac{1}{4}$.

Both are mathematically correct since $\frac{2}{4} = \frac{1}{2}$! However, check the answer choices - if $\frac{2}{4}$ is listed, choose that one even though $\frac{1}{2}$ is simplified.

Yes, but it's harder! You'd need to convert $\frac{3}{4}$ to eighths: $\frac{6}{8} - \frac{2}{8} = \frac{4}{8} = \frac{1}{2}$. Simplifying first keeps the numbers smaller and easier to work with.

Substitute your answer back into the original equation. If you got $\frac{2}{4}$, check: $\frac{2}{4} + \frac{2}{8} = \frac{2}{4} + \frac{1}{4} = \frac{3}{4}$ ✓
