1. Masla samajhna: Reciprocal ka matlab hota hai kisi number ka ulta ya inverse. 2. Formula: Agar kisi number ko $x$ kaha jaye, to uska reciprocal hota hai $\frac{1}{x}$. 3. Misal: Agar $x=5$, to iska reciprocal hoga $\frac{1}{5}$. 4. Important rule: Kisi bhi number ka reciprocal us number ko 1 se divide karne se milta hai. 5. Agar number zero ho, to uska reciprocal nahi hota kyun ke zero se divide karna mumkin nahi. 6. Reciprocal ka use fractions ko simplify karne aur equations solve karne mein hota hai. 7. Summary: Reciprocal ka matlab hai $\frac{1}{x}$ jahan $x$ wo number hai jiska reciprocal lena hai.
