(The four equal parts of a circle)
A circle, divided into four equal parts, was given to Arun, Tharun, Sankar, and Gopi to colour. They finished the task in two minutes, as shown in the pictures below. In the given images, one fourth (quarter) of the portion was coloured by Tharun.

Question. Who coloured 1/2 portion of the circle?
Answer: Arun coloured 1/2 portion of the circle. This means Arun shaded two out of the four equal parts. Half of something is the same as two quarters.
In simple words: Arun coloured half of the circle.

🎯 Exam Tip: Always relate fractions to the total number of parts. One-half is equivalent to two-fourths.

Question. Who coloured the whole portion of the circle?
Answer: Sankar coloured the whole portion of the circle. This means Sankar shaded all four out of the four equal parts. The whole circle is represented by \( \frac{4}{4} \) or 1.
In simple words: Sankar coloured the entire circle.

🎯 Exam Tip: Remember that "whole" means 1, which can be written as a fraction where the numerator and denominator are the same, like \( \frac{4}{4} \).

Question. Who coloured three fourth of the portion of the circle?
Answer: Gopi coloured three fourth of the portion of the circle. This means Gopi shaded three out of the four equal parts. The fraction \( \frac{3}{4} \) shows that three quarters of the circle are coloured.
In simple words: Gopi coloured three-quarters of the circle.

🎯 Exam Tip: Visualizing fractions helps understand them. Three-fourths looks like almost a full circle, with just one part left uncoloured.
