Answer 1

let denominator to be x, numerator = y
\[\frac{ y+1 }{ x }= \frac{ 2 }{ 3 }\]
Solve this and make an equation.
Cnan u do it?

Answer 2

after u do this for second part it says numerator and denominatoe both increase
\[\frac{ y+5 }{ x+5 }= \frac{ 7 }{ 10 }\]

Answer 3

after u solve this you will get 2 equations.. solve them simultaneously
