Answer:
The answer is y=-15
Step-by-step explanation:
In order to determine the number, we have to express the problem into an equation. Every time that we want to know a value of a variable, we have to express an equation that it contains the variable.
Let's express every part of the statement:
Three fifths=[tex]\frac{3}{5}[/tex]
A number= y
negative 9= -9
Putting together every part into an equation:
[tex]\frac{3}{5}y=-9\\y=\frac{5}{3}*(-9)\\y=5*(-3)\\y=-15[/tex]
Finally, the value of the number "y" is -15.
