Question

what should be subtracted from (4/5 - 3/4) to get -1/5 ?​

Answer 1

Answer:

1/4

4/5-3/4-1/5

LCM : 20

16-15-4

16+4 = 20

20-15 = 5

5/20 = 1/5

Answer 2

Answer:

3/20

Explanation:

4/5-3/4 = 16/20-15/20 [L.C.M. of 5 and 4 = 20]

= 1/20

ATQ...

Let the number that should be subtracted be n.

(4/5-3/4) - n = -1/5

1/20 - n = -1/5

-n = -1/5 - 1/20

-n = -4/20 - 1/20 [L.C.M. of 5 and 20 = 20]

-n = -3/20

n= 3/20

Therefore, 3/20 should be subtracted from (4/5-3/4) to get -1/5..
