Question

what should be added to (2/3+3/5)to get-2/15...​

Answer 1

Answer:

-21/15

Step-by-step explanation:

consider the number to be added as x,

now the eqn would be

x+(2/3+3/5)= -2/15

by taking lcm and adding the term inside the bracket, we get,

x+(19/15)= -2/15

now keep the x on left side and the numeric term to right side,

x= (-2/15 )-(-19/15)

now by adding we get ,

x= -21/15

thus the number to be added with (2/3+3/5) to get -2/15 is -21/15
