Question

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

Answer 1

Answer:

Step-by-step explanation:

11 / 12 - x = - 3 / 4

x = 11 / 12 + 3 / 4

x = 11 / 12 + 9 / 12

x = (11 + 9) / 12

x = 20 / 12

x = 5×4 / 3×4

x = 5 / 3

thus 5 / 3 should be subtracted from

11 / 12 to give - 3 / 4.

Answer 2

The number is 5/3.

Given:

• Two numbers 11/12 and -3/4.

To find:

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

Solution:

Concept to be used:

1. Assume the number as variable.
2. Write equation from the statement.
3. Solve the equation.

Step 1:

Write equation from the statement.

Let the number is x.

So,

$\bf \frac{11}{12} - x = - \frac{3}{4}$

Step 2:

Solve the equation.

$\frac{11 - 12x}{12} = - \frac{3}{4}$

or

$\frac{11 - 12x}{3} = - \frac{3}{1}$

or

$11 - 12x = - 9$

or

$- 12x = - 9 - 11$

or

$12x = 20$

or

$x = \frac{20}{12}$

or

$\bf x = \frac{5}{3}$

Thus,

The number is 5/3.
