Question

What should be subtracted from -3/7 to get -2/5

Answer 1

Answer:

Step-by-step explanation:

Let the number that should be subtracted from be 'x'

x - (-3/7) = -2/5

x = -2/5 + (-3/7)

  = LCM of denominators i.e. 7 and 5 = 35

  = Multiply both with the number that should be number suitable to get 35

  = -2\5 x 7\7 = -14/35                                        = -3/7 x 5/5 = -15/35

 -14/35 + -15/35 = -29/35

  Therefore, -29/35 is the number that should be subtracted from -3/7
