Question

Write these fractions appropriately as additions or subtractions:

(a)

(b)

(c)

Answer 1

(a) Here, it can be observed that 1^st, 2^nd, and 3^rd rectangles are representing 1, 2, and 3 shaded parts out of 5 equal parts respectively. Clearly, the fraction represented by 3^rd rectangle is the sum of the fractions represented by 1^st and 2^nd rectangles.

Hence,

(b) Here, it can be observed that 1^st, 2^nd, and 3^rd circles are representing 5, 3, and 2 shaded parts out of 5 equal parts respectively. Clearly, the fraction represented by 3^rd circle is the difference between the fractions represented by 1^st and 2^nd circles.

Hence,

(c) Here, it can be observed that 1^st, 2^nd, and 3^rd rectangles are representing 2, 3, and 5 shaded parts out of 6 equal parts respectively. Clearly, the fraction represented by 3^rd rectangle is the sum of the fractions represented by 1^st and 2^nd rectangles.

Hence,
