Question

$\frac{3}{7} + \frac{3}{4}$
answer the above question​

Answer 1

$\frac{3}{7} + \frac{3}{4}$

$=$

$lcm \: of \: 7 \: and \: 4 = 28$

$=$

$\frac{4 \times 3 + 7 \times 3}{28}$

$=$

$\frac{12 + 21}{28}$

$=$

33/28

ANOTHER METHOD...

AS WE KNOW THE LCM IS 28

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

$\frac{3 \times 7}{4 \times 7} = \frac{21}{28}$

now add the both no.

=

$\frac{12 + 21}{28}$

$=$

$\frac{33}{28}$
