Question 1.Write the fractions appropriately as additions or subtractions

 

 

 

Answer:

(a) {tex}\frac{1}{5} + \frac{2}{5} = \frac{{1 + 2}}{5} = \frac{3}{5}{/tex}

(b) {tex}\frac{5}{5} – \frac{3}{5} = \frac{{5 – 3}}{5} = \frac{2}{5}{/tex}

(c) {tex}\frac{2}{6} + \frac{3}{6} = \frac{{2 + 3}}{6} = \frac{5}{6}{/tex}

Question 2.Solve:

(a) {tex}\frac{1}{{18}} + \frac{1}{{18}}{/tex}

(b) {tex}\frac{8}{{15}} + \frac{3}{{15}}{/tex}

(c) {tex}\frac{7}{7} – \frac{5}{7}{/tex}

(d) {tex}\frac{1}{{22}} + \frac{{21}}{{22}}{/tex}

(e) {tex}\frac{{12}}{{15}} – \frac{7}{{15}}{/tex}

(f) {tex}\frac{5}{8} + \frac{3}{8}{/tex}

(g) {tex}1 – \frac{2}{3}\left( {1 = \frac{3}{3}} \right){/tex}

(h) {tex}\frac{1}{4} + \frac{0}{4}{/tex}

(i) {tex}3 – \frac{{12}}{5}{/tex}

Answer:

(a) {tex}\frac{1}{18}+\frac{1}{18}=\frac{1+1}{18}=\frac{2}{18}=\frac{1}{9}{/tex}

(b) {tex}\frac{8}{15}+\frac{3}{15}=\frac{8+3}{15}=\frac{11}{15}{/tex}

(c) {tex}\frac{7}{7}-\frac{5}{7}=\frac{7-5}{7}=\frac{2}{7}{/tex}

(d) {tex}\frac{1}{22}+\frac{21}{22}=\frac{1+21}{22}=\frac{22}{22}=1{/tex}

(e) {tex}\frac{12}{15}-\frac{7}{15}=\frac{12-7}{15}=\frac{5}{15}=\frac{1}{3}{/tex}

(f) {tex}\frac{5}{8}+\frac{3}{8}=\frac{8}{8}=1{/tex}

(g) {tex}1-\frac{2}{3}=\frac{3}{3}-\frac{2}{3}=\frac{3-2}{2}=\frac{1}{3}{/tex}

(h) {tex}\frac{1}{4}+\frac{0}{4}=\frac{1+0}{4}=\frac{1}{4}{/tex}

(i) {tex}3-\frac{12}{5}=\frac{15}{5}-\frac{12}{5}=\frac{15-12}{5}=\frac{3}{5}{/tex}

NCERT Solutions for Class 6 Maths Exercise 7.5

Question 3.Shubham painted {tex}\frac{2}{3}{/tex} of the wall space in his room. His sister Madhavi helped and painted {tex}\frac{1}{3}{/tex} of the wall space. How much did they paint together?

Answer:

Fraction of wall painted by Shubham = {tex}\frac{2}{3}{/tex}

Fraction of wall painted by Madhavi = {tex}\frac{1}{3}{/tex}

Total painting by both of them = {tex}\frac{2}{3}+\frac{1}{3}=\frac{2+1}{3}=\frac{3}{3}=1{/tex}

Therefore, they painted complete wall.

Question 4.Fill in the missing fractions:

(a) {tex}\frac{7}{{10}} – \boxed{{\text{ }}} = \frac{3}{{10}}{/tex}

(b) {tex}\boxed{{\text{ }}} – \frac{3}{{21}} = \frac{5}{{21}}{/tex}

(c) {tex}\boxed{{\text{ }}} – \frac{3}{6} = \frac{3}{6}{/tex}

(d) {tex}\boxed{{\text{ }}} + \frac{5}{{27}} = \frac{{12}}{{27}}{/tex}

Answer:

(a) {tex}\frac{4}{{10}}{/tex}

(b) {tex}\frac{8}{{21}}{/tex}

(c) {tex}\frac{6}{6}{/tex}

(d) {tex}\frac{7}{{27}}{/tex}

NCERT Solutions for Class 6 Maths Exercise 7.5

Question 5.Javed was given of a basket of oranges. What fraction of oranges was left in the basket?

Answer:

Total = 1

Fraction of Orange left = {tex}1 – \frac{5}{7}{/tex}

= {tex}\frac{7}{7} – \frac{5}{7} = \frac{{7 – 5}}{7} = \frac{2}{7}{/tex}

Thus, {tex}\frac{2}{7}{/tex} oranges was left in the basket.
