Question

What should be subtracted from ( 3/4 - 2/3 ) to get - 11/4

Answer 1

Step-by-step explanation:

Hi,

3/4 - 2/3

Lcm of 4 and 3 = 12

Now,

3*3 - 2*4/12

9-8/12 = 1/12

(3/4-2/3) = 1/12.

Now,

What should be subtracted from 1/12 to get -11/4.

Let x should be subtracted from 1/12 to get -11/4

Then,

1/12 - x = -11/4

1 - 12x/12 = -11/4

4(1-2x) = 12*(-11)

4 - 8x = -132

-8x = -132-4

-8x = -136

x = 136/8 = 17

Hence,

17 should be subtracted from 1/12 to get -11/4.

Hope it will help you:)

Answer 2

Answer:

• According to the questions, we must check what should be subtracted from ( 3/4 - 2/3 ) to get - 11/4.

The steps as follows, is just like verifying our answer. That's finding what would be the number which helps us to get some other number.

= (3/4 - 2/3) - x = -11/4

= (9 - 8)/12 - x = -11/4

= 1/12 - x = -11/4

= [(1 - 12)/(12)] = -11/4

= [4 (1-2) = 12 (-11)]

= 4 - 8 = -132

= -8 = -132 - 4

= -8 = -136

= 136/8

= 17

Therefore, 17 is the fractional number.
