Answer:
Correct option is:
a. 3/2
Step-by-step explanation:
We have to determine the number which must be multiplied to the equation
[tex]\dfrac{2}{3}x=10[/tex]
to form the equation x=15
Clearly the left hand side of the equation is converted to x
Hence, on multiplying the original equation by 3/2, we get
[tex]\dfrac{2}{3}x\times \dfrac{3}{2}=10\times \dfrac{3}{2}[/tex]
which is equal to
x=15
Hence, Correct option is:
a. 3/2
