Cost of one item when three cost Rs 15
Rs 5
💡 What it's asking: We know the price of a few same items together and want the price of just one. Sharing equally means dividing.
- Write the total cost: Rs 15.
- Count the items: 3.
- Divide to share the cost equally: 15 ÷ 3 = 5.
- So one item costs Rs 5.
✅ Three items at Rs 5 each cost 3 × 5 = Rs 15, which matches.

සමාන අයිතම කිහිපයක මුළු මිල දී ඇත; එකක මිල සොයන්න. සමව බෙදීම යනු බෙදීමයි.
- මුළු මිල ලියන්න: රු. 15.
- අයිතම ගණන: 3.
- සමව බෙදීමට බෙදන්න: 15 ÷ 3 = 5.
- එබැවින් එකක මිල රු. 5 යි.
Add two fractions with the same denominator
5/7
💡 What it's asking: Both fractions are made of sevenths, so we are just counting sevenths.
- Check the denominators: both are 7, so the pieces are the same size.
- Add the numerators: 3 + 2 = 5.
- Keep the denominator 7.
- Answer: 5/7.
✅ 3 sevenths and 2 sevenths make 5 sevenths, less than one whole, which is sensible.

- හර බලන්න: දෙකම 7; කොටස් එකම ප්රමාණයයි.
- ලව එකතු කරන්න: 3 + 2 = 5.
- හරය 7 ලෙසම තබන්න.
- පිළිතුර: 5/7.
