∴ (shading triangles = 6)

iii) \(\frac{3}{5}\) of the squares in box (c).
Solution:
KSEEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.2 13
Total squares = 5 × 3 = 15
we need to shade \(\frac{3}{5}\) squares.
number of squares to shade
KSEEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.2 14
(∴ So shading squares = 9)
