Add this fraction 5/4 + 3/7

$\Large{\bf{\pink{\mathfrak{\dag{\underline{\underline{Solution :}}}}}}}$

✠ As the denominators are different we have to take thr LCM. As they don't have any common factors so we will directly multiply. 4 × 7 = 28.

$\displaystyle{ \implies \: \frac{5 \times 7}{4 \times 7} = \frac{35}{28} }$

$\displaystyle{ \implies \: \frac{3 \times 4}{7 \times 4} = \frac{12}{28} }$

According to the question,

$\displaystyle{ \implies \: \frac{35 + 12}{28} }$

$\displaystyle{ \implies \: \frac{47}{28} }$

∴ 47/28 is the answer.
