Solve this question :

$\frac{3}{4} + \frac{5}{6} + ( - \frac{7}{12} )$

$\color {red} </p><p>\Large \underline {\underline {Answer \: :}}$

$\frac{3}{4} + \frac{5}{6} + ( - \frac{7}{12} )$

$\frac{3}{4} + \frac{5}{6} - \frac{7}{12}$

$\frac{9 + 10 - 7}{12}$

$= \frac{12}{12}$

$= 1$

$\implies$ Answer is 1.

Answer 2

Answer:

-2508

Step-by-step explanation:

3 x 4 + 5 x 6 (-7 x 12)

First you multiply -7 and 12 which is -84 so it will be like this

3 x 4 + 5 x 6 x (-84)

Next you multiply 3 and 4 which is 12  so it will go like this

12 + 5 x 6 x (-84)

After that you will do 5 x 6 which is 30 it will be like this

12 + 30 x (-84)

Then you will multiply 30 by -84 which will be -2520 it will be like this

12 - 2520

Then you will minus which will give you -2508
