KSEEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.3 36
Solution:
KSEEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.3 37
Now,
we have to find greater of
KSEEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.3 38
To compare fractions, we make denominator equal.

ii)
KSEEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.3 41
Solution:
KSEEB Solutions for Class 7 Maths Chapter 2 Fractions and Decimals Ex 2.3 42
Now,
we have to find greater of \(\frac{3}{7}\) & \(\frac{2}{7}\)
Since denominator is same, number with greater numerator is greater.i.e., \(\frac{3}{7}>\frac{2}{7}\)
∴ Thus \(\frac{1}{2}\) of \(\frac{6}{7}\) is greater
