Question

22. What number should be subtracted from -7/10 to get 11/30 ?​

Answer 1

Answer:

∴ x = -16/15

Step-by-step explanation:

Solution,

 -7/10 - x = 11/30

or, -x = 11/30 + 7/10

or, -x = 11/30 + (7×3/10×3)

or, -x = 11/30 + 21/30

or, -x = (11+21)/30

or, -x = 32/30

or, -x = 16/15

∴ x = -16/15

Answer 2

Answer:

x= -16/15

Step-by-step explanation:

Let the no. be x

=. -7/10 - x = 11/30

=. -21/30 - x = 11/30

By substituting x to other side

=. -21/30 - 11/30 = x

=. x = -32/30 = -16/15
