Question

$\frac{2}{3}+\underline{quadquad}=8$

Explanation:

Step1: Let the unknown be \( x \), the equation is \( \frac{2}{3}+x = 5 \)

Step2: Solve for \( x \), subtract \( \frac{2}{3} \) from both sides: \( x=5 - \frac{2}{3} \)

Step3: Calculate \( 5-\frac{2}{3}=\frac{15}{3}-\frac{2}{3}=\frac{13}{3} \)

Answer:

\( \frac{13}{3} \) (or \( 4\frac{1}{3} \))
