Question

What number should be subtracted from mines 3 by 4 to get mines 1 by 2

Answer 1

Answer:

(-3/4)-x=(-1/2)

(-3-4x)/4=(-1/2)

2(-3-4x)=4(-1)

-6-8x= -4

-8x = -4+6

-8x= 2

x=-2/8

x= -1/4

Answer 2

Answer:

-5/2

Thus the number that should be subtracted from (-3) / 4 to get (-1) / 2 is = x = -5/2

Step-by-step explanation:

Let the number that should be subtracted from (-3)/4 to get (-1)/2 be 'x'. Then,

According to the question,

x - (-3) / 4 = (-1) / 2

On solving this, we get

=> x + 3/4 = (-1) / 2

=> x = (-1) / 2 - 3/4

On taking the LCM of 2 and 4 = 4 on the RHS, we get,

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

=> x = -5/4

Hence, the value of x = -5/4

Thus the number that should be subtracted from (-3) / 4 to get (-1) / 2 is = x = -5/2
