DAV Class 3 Maths Ch 11 WS 5 Solutions
Question 1.
Find the difference.
(a) \(\frac{7}{9}-\frac{2}{9}\)
Solution:
\(\frac{7}{9}-\frac{2}{9}\)
= \(\frac{7-2}{9}\)
= \(\frac{5}{9}\)
(b) \(\frac{7}{10}-\frac{4}{10}\)
Solution:
\(\frac{7}{10}-\frac{4}{10}\)
= \(\frac{7-4}{10}\)
= \(\frac{3}{10}\)
(c) \(\frac{5}{8}-\frac{3}{8}\)
Solution:
\(\frac{5}{8}-\frac{3}{8}\)
= \(\frac{5-3}{8}\)
= \(\frac{2}{8}\)
(d) \(\frac{5}{7}-\frac{1}{7}\)
Solution:
\(\frac{5}{7}-\frac{1}{7}\)
= \(\frac{5-1}{7}\)
= \(\frac{4}{7}\)
(e) \(\frac{4}{5}-\frac{3}{5}\)
Solution:
\(\frac{4}{5}-\frac{3}{5}\)
= \(\frac{4-3}{5}\)
= \(\frac{1}{5}\)
(f) \(\frac{8}{9}-\frac{3}{9}\)
Solution:
\(\frac{8}{9}-\frac{3}{9}\)
= \(\frac{8-3}{9}\)
= \(\frac{5}{9}\)
Question 2.
Subtract the following fractions:
(a) \(\frac{2}{8}\) from \(\frac{6}{8}\)
Solution:
\(\frac{6}{8}-\frac{2}{8}\)
= \(\frac{6-2}{8}\)
= \(\frac{4}{8}\)
(b) \(\frac{8}{9}\) from \(\frac{9}{9}\)
Solution:
\(\frac{9}{9}-\frac{8}{9}\)
= \(\frac{9-8}{9}\)
= \(\frac{1}{9}\)
(c) \(\frac{3}{7}\) from \(\frac{6}{7}\)
Solution:
\(\frac{6}{7}-\frac{3}{7}\)
= \(\frac{6-3}{7}\)
= \(\frac{3}{7}\)
(d) \(\frac{3}{8}\) from \(\frac{7}{8}\)
Solution:
\(\frac{7}{8}-\frac{3}{8}\)
= \(\frac{7-3}{8}\)
= \(\frac{4}{8}\)
(e) \(\frac{1}{10}\) from \(\frac{9}{10}\)
Solution:
\(\frac{9}{10}-\frac{1}{10}\)
= \(\frac{9-1}{10}\)
= \(\frac{8}{10}\)
(f) \(\frac{2}{5}\) from \(\frac{4}{5}\)
Solution:
\(\frac{4}{5}-\frac{2}{5}\)
= \(\frac{4-2}{5}\)
= \(\frac{2}{5}\)
Question 3.
Colour squares to show the correct answer.
(a) \(\frac{3}{5}-\frac{1}{5}\) = 
Solution:
\(\frac{2}{5}\) = 
(b) \(\frac{1}{4}-\frac{1}{4}\) = 
Solution:
0 = 
(c) \(\frac{7}{9}-\frac{2}{9}\) = 
Solution:
\(\frac{5}{9}\) = 
(d) \(\frac{3}{3}-\frac{2}{3}\) = 
Solution:
\(\frac{1}{3}\) = 
(e) \(\frac{5}{10}-\frac{4}{10}\) = 
Solution:
\(\frac{1}{10}\) = 
(f) \(\frac{9}{9}-\frac{6}{9}\) = 
Solution:
\(\frac{3}{9}\) = 
DAV Class 3 Maths Chapter 11 Value Based Questions
There was a fair …………………. by the police.
Question 1.
What fraction of the victims were rescued?
Solution:
Authorities sent victims to hospital = \(\frac{4}{7}\)
Fraction of victims sent to hospital by villagers = \(\frac{2}{7}\)
Fraction of victims were rescued = \(\frac{4}{7}\) + \(\frac{2}{7}\)
= \(\frac{6}{7}\)
Question 2.
If you were in that situation what would you have done?
Solution:
I would have moved to a safer place and ask others also to be calm.

E.g. Subtract \(\frac{1}{3}\) from \(\frac{7}{3}\)
Solution:
\(\frac{7}{3}\) – \(\frac{1}{3}\)
= \(\frac{7-1}{3}\)
= \(\frac{6}{3}\)
Subtract the numerators.
Keep the dcnominator as it is.
