Question

what number should be subtracted from -5/2 so to get 3/4​

Answer 1

Answer:

-13/4

Step-by-step explanation:

let the no. to be subtracted be x

so,

-5/2 - x= 3/4

x= -5/2 - 3/4

lcm =4

x= -(10 -3 )/4

x= -13/4

Answer 2

Answer:

-13/4

Step-by-step explanation:

Let the unknown number be 'x'

∴ -5/2 - x = 3/4

⇒ -x = 3/4 + 5/2 (Changing -5/2 to the other side, gets rid of minus sign)

⇒ -x = (3+10)/4 (Taking Lowest Common Multiple (LCM) of 2 and 4, i.e. 4)

⇒ -x = 13/4

⇒ x = -13/4 (Bringing minus sign to the other side)

∴ The unknown number 'x' is -13/4
