Answer:
Step-by-step explanation:
let the product of x and y be 35
∴xy=35
⇒y=35/x..........................................(1)
let the product of y and z be 63
∴yz=63
⇒y=63/z....................................(2)
from (1) and (2)
35/x=63/z
⇒63x=35z
⇒x/z=35/63=5/9
∴(x)(y)=35
⇒5y=35
⇒y=7
∴(y)(z)=63
⇒(y)9=63
⇒y=7
∴y =7
∴The second number is 7.
