Answer:
Given that product the of a rational number with
3
−4
is
16
−9
Let the rational number be y
∴y×
3
−4
=
16
−9
By cross multiplication,
y=
4×16
9×3
=
64
27
Answer:
-25/14
Step-by-step explanation:
given, (-7/20)(x) = 5/8
=> x = - (5/8) * (20/7)
=> x = - (5/2) * (5/7)
=> x = - (5*5)/(2*7)
=> x = -25/14
