Question

Which number should be subtracted from 11/12 so that we obtain -3/4

Answer 1

your answer...... .....

Answer 2

Let a number be x which should be subtracted from 11/12 to get (-3)/4

Now,

If we express the situation mathematically we obtain :-

$\frac{11}{12} - x = \frac{( - 3)}{4} \\ \\ \\ \frac{11 - 12x}{12} = \frac{ - 3}{4} \\ \\ \\ \\4(11 - 12x) = 12( - 3) \\ \\ \\44 - 48x = - 36 \\ \\ \\ \\48x = 44 + 36 \\ \\ \\48x = 80 \\ \\ \\x = \frac{80}{48} \\ \\ \\x = \frac{5}{3}$

Hence,

5/3 must be subtracted from 11/12 to obtain (-3)/4

We adopt the general method of cross multiplication and convert the situation into a simple linear equation in one variable and solve for the variable.

The solution obtained gives us the answer of the question.

Answer= 5/3
