Question

answer the following
7/9+5/12​

Answer 1

So we multiply 7 by 12, and get 84. Then we multiply 5 by 9, and get 45. Next we give both terms new denominators -- 9 × 12 = 108.

Answer 2

$\huge{❥}\:{\mathtt{{\purple{\boxed{\tt{\pink{\red{A}\pink{n}\orange{s}\green{w}\blue{e}\purple{r᭄}}}}}}}}❥$

$\frac{7}{9} + \frac{5}{12}$

$= \frac{7 \times 12 + 2 \times 9}{9 \times 12}$

$= \frac{84 + 18}{108}$

$= \frac{102}{108}$

$= \frac{51}{54}$

Hence This is the required answer. . . . . . .

Answer 3

$\huge{❥}\:{\mathtt{{\purple{\boxed{\tt{\pink{\red{A}\pink{n}\orange{s}\green{w}\blue{e}\purple{r᭄}}}}}}}}❥$

$\frac{7}{9} + \frac{5}{12}$

$= \frac{7 \times 12 + 2 \times 9}{9 \times 12}$

$= \frac{84 + 18}{108}$

$= \frac{102}{108}$

$= \frac{51}{54}$

Hence the required answer. . . . . . .
