Question

what should be subtracted from (2by3 +1by4) to get -1by2 ?​

Answer 1

Step-by-step explanation:

We subtract 1/4 from 3/4-2/3

to get -1/6

3/4-2/6 we get 1/12

let the no. that subtract is n then 1/12-n =-1/6

then when we solve we get 6-36n=-12

-72n = -12-6

then n = 18/72

1/4

Answer 2

Answer:

needed number is 17/5

Step-by-step explanation:

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

([8 + 3]/12) - x = -1/2

11/12 - x = -1/2

11/12 + 1/2 = x

(11 + 6)/12 = x

17/12 = x
