let the number=x

Step-by-step explanation:

x into -7/8=-1/2

x=-1/2 into -8/7

lcm of 2 and 7 =14

-7 into -16/14

+112/14

Answer 2

Answer:

4/7

Step-by-step explanation:

let the number required be x

according to the problem

We multiply with (-7/8) to get -1/2

x(-7/8)=-1/2

by cross multiply we get

14x=8

so the required value is i.e..

x=8/14

=4/7

therefore the required number is 4/7
