Question

What should be added to (1/2+1/3+1/4)
to get-1?​

Answer 1

Answer:

-25/12 should be added to (1/2+1/3+1/4)  to get -1.

Step-by-step explanation:

Set up an equation.

$(\frac{1}{2} + \frac{1}{3} + \frac{1}{4}) + x = -1$

Simplify by combining the fractions under a common denominator.

$(\frac{6}{12} + \frac{4}{12} + \frac{3}{12}) + x = -1\\\\(\frac{6+4+3}{12}) + x = -1\\\\(\frac{13}{12}) + x = -1$

We are solving for 'x'.

$\frac{13}{12} + x = -1\\\\x = -1 - \frac{13}{12}\\\\x = -\frac{12}{12} - \frac{13}{12}\\\\x = \frac{-12-13}{12}\\\\x = -\frac{25}{12}$

∴ -25/12 should be added to (1/2+1/3+1/4)  to get -1.

Answer 2

Answer:

let the number Be x

we should multiply the (3×4)=12

(12+2+(-1) =15

now at all the 1 number there are 4 one so

answer is (15/
