Question

solution of the sum 5 upon 12 + 7 upon 16

Answer 1

5/12+7/16
L.C.M=48
Therefore , 5×4/48 and 7×3/48
=20/48+21/48
=41/48

Answer 2

Solution of $\frac{5}{12}+\frac{7}{16}$ = $\frac{41}{48}$.

• We have to find the solution of the fraction $\frac{5}{12}+ \frac{7}{16}$.
• In order to perform addition of numerators , we need to make the denominators equal.
• Making the denominators equal ,

$\frac{5}{12}+ \frac{7}{16}$

(LCM of 12 and 16 is 48)

= $(\frac{5}{12}).(\frac{4}{4})+ (\frac{7}{16}).(\frac{3}{3})$  (Making the denominators equal)

= $\frac{20}{48}+ \frac{21}{48}$  (Denominators are equal so we can add the numerators )

= $\frac{20 + 21}{48}$

= $\frac{41}{48}$
