Fraction questions for class 6 (solved examples)

Example 1: Make equivalent fractions by multiplying the numerator and denominator by the given number.

(a)

$\frac{2}{3}$ by 4 (b) $\frac{3}{7}$ by 5

Sol. (a) $\frac{2}{3}=\frac{2 \times 4}{3\times 4}=\frac{8}{12}$ Ans. $\frac{2}{3}$ and $\frac{8}{12}$ are equivalent fractions.

(b) $\frac{3}{7}=\frac{3\times 5}{7\times 5}=\frac{15}{35}$ Ans. $\frac{3}{7}$ and $\frac{15}{35}$ are equivalent fractions.

Example 2 : Make equivalent fractions by dividing the numerator and denominator by the given number.

(a) $\frac{12}{36}$ by 3 (b) $\frac{6}{14}$ by 2

Sol. (a) $\frac{12}{36}=\frac{12/3}{36/3}=\frac{4}{12}$ Ans. $\frac{12}{36}$ and $\frac{4}{12}$ are equivalent fractions.

(b) $\frac{6}{14}=\frac{6/2}{14/2}=\frac{3}{7}$ Ans. $\frac{6}{14}$ and $\frac{3}{7}$ are equivalent fractions.

Example 3: Fill in each box to make equivalent fractions.

(a) $\frac{1}{2}=\frac{\square }{10}$ (b) $\frac{6}{14} =\frac{\square }{7}=\frac{9}{\square }=\frac{15}{\square }$

Sol. (a) $\frac{1\times 5}{2\times 5}=\frac{\left [ 5 \right ]}{10}$

(b) $\frac{6}{14}=\frac{6/2}{14/2}=\frac{\left [ 3 \right ]}{7}, \, \, \frac{3\times 3}{7\times 3}=\frac{9}{\left [ 21 \right ]},\, \, \, \frac{3\times 5}{7\times 5}=\frac{15}{\left [ 35 \right ]}$ . Thus $\frac{6}{14} =\frac{\left [ 3 \right ] }{7}=\frac{9}{\left [ 21 \right ]}=\frac{15}{\left [ 35 \right ] }$

Example 4: Write $\frac{6}{10},\frac{5}{10},\frac{2}{10}\, \, and\, \frac{7}{10}$ in ascending order.

Sol. The fractions $\frac{6}{10},\frac{5}{10},\frac{2}{10}\, \, and\, \frac{7}{10}$ are like fractions. Let us compare their numerators.

Since 2<5<6<7. Therefore $\frac{2}{10}< \frac{5}{10}< \frac{6}{10}< \frac{7}{10}$ .

Example 5: Arrange the following fractions in descending order. $\frac{3}{2}, \frac{1}{2}, \frac{7}{10}, \frac{5}{6}$

Sol. The given fractions are unlike fractions. So we shall change them into equivalent fractions with common denominator, which is the LCM of 5, 2, 10,6 .

LCM of 5, 2, 10, 6 are 30 .

Changing each of the given fractions into equivalent fraction with denominator 30, we get

$\frac{3}{5} =\frac{3\times 6}{5\times 6}=\frac{18}{30}$ , $\frac{1}{2}=\frac{1\times 15}{2\times 15}=\frac{15}{30}$ , $\frac{7}{10}=\frac{7\times 3}{10\times 3}=\frac{21}{30}$ , $\frac{5}{6}=\frac{5\times5}{6\times 5}=\frac{25}{30}$

Clearly , $\frac{25}{30}>\frac{21}{30}>\frac{18}{30}>\frac{15}{30}$ .

Hence , the given fractions in descending order are $\frac{5}{6}>\frac{7}{10}>\frac{3}{5}>\frac{1}{2}$

Example 6: Add $3\frac{1}{2}$ and $4\frac{1}{5}$ .

Sol. Change mixed numbers to improper fractions, $3\frac{1}{2}=\frac{7}{2}$ and $4\frac{1}{5}=\frac{21}{5}$ .

Now Convert unlike fractions to like fractions with the same denominator 10 (LCM of 2 and 5) and add them

$\frac{7\times 5}{2\times 5}=\frac{35}{10},\, \, \, \, \frac{21\times 2}{5\times 2}=\frac{42}{10}$ .

Hence $3\frac{1}{2}+4\frac{1}{5}=\frac{7}{2}+\frac{21}{5}=\frac{35}{10}+\frac{42}{10}=\frac{77}{10}=7\frac{7}{10}$ Ans. $7\frac{7}{10}$

Example 7: Aditya mixed $2\frac{1}{8}$ L of green paint with $3\frac{5}{16}$ L of red paint. How much paint does he have now?

Sol. Quantity of green paint = $2\frac{1}{8}$ L

quantity of red paint= $3\frac{5}{16}$ L

Total quantity of paint= $2\frac{1}{8}$ L + $3\frac{5}{16}$ L = $\frac{17}{8}$ L + $\frac{53}{16}$ L

The LCM of 8 and 16 =16, $\frac{17}{8}=\frac{17\times 2}{8\times 2}=\frac{34}{16}$

So, $\frac{17}{8}$ + $\frac{53}{16}$ = $\frac{34}{16}+\frac{53}{16}=\frac{34+53}{16}=\frac{87}{16}=5\frac{7}{6}$

Ans. Aditya has $5\frac{7}{16}$ L of paint.

Example 8: Simplify $\frac{7}{9}-\frac{2}{3}+\frac{5}{6}$

Sol. LCM of 9, 3, 6 is 18

Now $\frac{7}{9}=\frac{7 \times 2}{9\times 2}=\frac{14}{18}$

$\frac{2}{3}=\frac{2\times 6}{3\times 6}=\frac{12}{18}$

$\frac{5}{6}=\frac{5\times 3}{6\times 3}=\frac{15}{18}$

$\frac{7}{9}-\frac{2}{3}+\frac{5}{6}$ = $\frac{14}{18}-\frac{12}{18}+\frac{15}{18}$ = $\frac{14-12+15}{18}=\frac{17}{18}$

Example 9: What must be subtracted from $6\frac{3}{4}$ to get $4\frac{1}{6}$ .

Sol. The fraction to be subtracted =- $6\frac{3}{4}$ – $4\frac{1}{6}$

= $\frac{27}{4}-\frac{25}{6}$

= $\frac{27\times 3}{4\times 3}-\frac{25\times 2}{6\times 2}$ = $\frac{81}{12}-\frac{50}{12}=\frac{81-50}{12}=\frac{31}{12}=2\frac{7}{12}$

Hence the required fraction to be subtracted is $2\frac{7}{12}$ .

Example 10: From a rope of 7 meters long, two pieces of length $2\frac{3}{5}$ meters and $3\frac{3}{10}$ meters were cut off. What is the length of the remaining rope?

Sol. Total length of the rope=7 meters

Total length cut off = $2\frac{3}{5} m+3\frac{3}{10} m=\frac{13}{5}m+\frac{33}{10} m$

= $\frac{26}{10}+\frac{33}{10}=\frac{59}{10}m$

Length of the remaining rope= $7-\frac{59}{10}=\frac{70}{10}-\frac{59}{10}=\frac{11}{10}m=1\frac{1}{10}m$

Hence, the length of the remaining rope is $1\frac{1}{10}m$ .
