Shade:
i) 1/2 of the circles in box (a)
ii) 2/3 of the triangles in box (b)
iii) 3/5 of the squares in box (c)

Solution:

(i) Total number of circles in box (a) = 12

1/2 of 12 circles = 1/2 × 12 = 6 circles

So, 6 circles should be shaded

(ii) Total number of triangles in box (b) = 9

2/3 of 9 triangles = 2/3 × 9 = 6 triangles

So, 6 triangles should be shaded.

iii) Total number of squares in box (c) = 15

3/5 of 15 squares = 3/5 × 15 = 3 × 3 = 9 squares

So, 9 squares should be shaded.
