$=\frac{29}{8}-\frac{29}{12}$
L.C.M of 8 and 12 = (2 × 2 × 2 × 3) = 24
$=\frac{(87-58)}{24}$
$=\frac{29}{24}$
$=1\frac{5}{24}$
$\Big(\frac{24}{8}=3,3\times29=87\Big)$
and $\Big(\frac{24}{12}=2,2\times29=58\Big)$

Find the equivalent fraction of $\frac{3}{5}$ having:
Denominator 30
AnswerLet, $\frac{3}{5}=\frac{\Box}{30}$
Clearly, 30 = 5 × 6
So, we multiply the numerator by 6
$\therefore\frac{3}{5}=\frac{3\times6}{5\times6}=\frac{18}{30}$
$\frac{3}{5}=\frac{18}{30}$
Hence, the required fraction is $\frac{18}{30}$.

Find the sum:
$\frac{7}{12}+\frac{9}{16}$
AnswerL.C.M. of 12 and 16 = (2 × 2 × 2 × 2 × 3) = 48
$\begin{array}{c|c}2&12,16\\\hline2&6,8\\\hline2&3,4\\\hline2&3,2\\\hline3&3,1\\\hline&1,1\end{array}$
Now, we know:
$\frac{7}{12}=\frac{7\times4}{12\times4}=\frac{28}{48}$
$\frac{9}{16}=\frac{9\times3}{16\times3}=\frac{27}{48}$
Therefore,
$\frac{7}{12}+\frac{9}{16}$
$=\frac{28}{48}+\frac{27}{48}$
$=\frac{(28+27)}{48}$
$=\frac{55}{48}$
$=1\frac{7}{48}$

Find the sum:
$\frac{4}{9}+\frac{8}{9}$
AnswerThe given fractions are like fractions
We know,
Sum of like fractions $=\frac{\text{Sum of the numerators}}{\text{Common denominator}}$
Thus, we have
$\frac{4}{9}+\frac{8}{9}$
$=\frac{(4+8)}{9}$
$=\frac{12}{9}$
$=\frac{4}{3}$
$=1\frac{1}{3}$

Find the equivalent fraction of $\frac{56}{70}$ with
Denominator 10
AnswerLet $\frac{56}{70}=\frac{\Box}{10}$
Clearly, 10 = 70 ÷ 7
So, we divide the numerator by 7
$\therefore\frac{56}{70}=\frac{56\div7}{70\div7}=\frac{8}{10}$
$\frac{56}{70}=\frac{8}{10}$
Hence, the required fraction is $\frac{8}{10}$.

Draw number lines and locate the following points:
$\frac{1}{4},\frac{1}{2},\frac{3}{4},\frac{4}{4}$
AnswerDraw a number line.
Mark 0 as the starting point and 1 as the ending point.
Then, divide 0 to 1 in four equal parts, where each part is equal to $\frac{1}{4}$.
Show the consecutive parts as $\frac{1}{4},\frac{1}{2},\frac{3}{4}$ and at 1 show $\frac{4}{4}$ = 1.
